Fix PCIe address ranges that are affected by recent PCI changes.
There are 3 additional patches pending that handle the backward
compatiblity inside the PCI subsystem, but the address ranges
should be fixed anyway.

This fixes multiple issues with the current non-existent PCIe clock setup:
The controller can run at up to 250MHz, so use a parent that provides this
clock.
The PHY needs an exact 100MHz reference clock to function if the PCIe
refclock is not fed in via the refclock pads. While this mode is not
supported (yet) in the driver it doesn't hurt to make sure we are
providing a clock with the right rate.
The AUX clock is specified to have a maximum clock rate of 10MHz. So
the current setup, which drives it straight from the 25MHz oscillator is
actually overclocking the AUX input.

On LS2088A-RDB board, if the spi-fsl-dspi driver is built as module
then its probe fails with the following warning:
[ 10.471363] couldn't get idr

[ 10.471708] fsl-dspi: probe of 2100000.spi failed with error -16
Reason for the failure is that bus-num property is set for dspi node.
However, bus-num property is not set for the qspi node. If probe for
spi-fsl-qspi happens first then id 0 is dynamically allocated to it.
Call to spi_register_controller() from spi-fsl-dspi driver then fails.
Since commit 29d2daf2c33c ("spi: spi-fsl-dspi: Make bus-num property
optional") bus-num property is optional. Remove bus-num property from
dspi node to fix the issue.

Both 1.8v and 3.3v power supplies can be used by i.MX8MQ PCIe PHY.
In default, the PCIE_VPH voltage is suggested to be 1.8v refer to data
sheet. When PCIE_VPH is supplied by 3.3v in the HW schematic design,
the VREG_BYPASS bits of GPR registers should be cleared from default

The PCIe host bridge on RK3399 advertises a single 64-bit memory
address range even though it lies entirely below 4GB.
Previously the OF PCI range parser treated 64-bit ranges more
leniently (i.e., as 32-bit), but since commit 9d57e61bf723 ("of/pci:
Add IORESOURCE_MEM_64 to resource flags for 64-bit memory addresses")
the code takes a stricter view and treats the ranges as advertised in
the device tree (i.e, as 64-bit).
The change in behaviour causes failure when allocating bus addresses
to devices connected behind a PCI-to-PCI bridge that require
non-prefetchable memory ranges. The allocation failure was observed
for certain Samsung NVMe drives connected to RockPro64 boards.
Update the host bridge window attributes to treat it as 32-bit address
memory. This fixes the allocation failure observed since commit
9d57e61bf723.

Putting the panel under the bridge chip (under the aux-bus node)
allows the panel driver to get access to the DP AUX bus, enabling all
sorts of fabulous new features.
While we're at this, get rid of a level of hierarchy for the panel
node. It doesn't need "ports / port" and can just have a "port" child.
For Linux, this patch has a hard requirement on the patches adding DP
AUX bus support to the ti-sn65dsi86 bridge chip driver. See the patch
("drm/bridge: ti-sn65dsi86: Add support for the DP AUX bus").

Scheduling a 32-bit application on a 64-bit-only CPU is a bad idea.
Ensure that 32-bit applications always take the slow-path when returning
to userspace on a system with mismatched support at EL0, so that we can
avoid trying to run on a 64-bit-only CPU and force a SIGKILL instead.

When confronted with a mixture of CPUs, some of which support 32-bit
applications and others which don't, we quite sensibly treat the system
as 64-bit only for userspace and prevent execve() of 32-bit binaries.
Unfortunately, some crazy folks have decided to build systems like this
with the intention of running 32-bit applications, so relax our
sanitisation logic to continue to advertise 32-bit support to userspace
on these systems and track the real 32-bit capable cores in a cpumask
instead. For now, the default behaviour remains but will be tied to
a command-line option in a later patch.

In preparation for late initialisation of the "sanitised" AArch32 register
state, move the AArch32 registers out of 'struct cpuinfo' and into their
own struct definition.

The hyp_page refcount is currently encoded on 4 bytes even though we
never need to count that many objects in a page. Make it 2 bytes to save
some space in the vmemmap.
As overflows are more likely to happen as well, make sure to catch those
with a BUG in the increment function.

Each struct hyp_page currently contains a pointer to a hyp_pool struct
where the page should be freed if its refcount reaches 0. However, this
information can always be inferred from the context in the EL2 code, so
drop the pointer to save a few bytes in the vmemmap.

We currently maintain two separate memory pools for the host stage-2,
one for pages used in the page-table when mapping memory regions, and
the other to map MMIO regions. The former is large enough to map all of
memory with page granularity and the latter can cover an arbitrary
portion of IPA space, but allows to 'recycle' pages.
However, this split makes accounting difficult to manage as pages at
intermediate levels of the page-table may be used to map both memory and
MMIO regions. Simplify the scheme by merging both pools into one. This
means we can now hit the -ENOMEM case in the memory abort path, but
we're still guaranteed forward-progress in the worst case by unmapping
MMIO regions. On the plus side this also means we can usually map a lot
more MMIO space at once if memory ranges happen to be mapped with block
mappings.

The list_head member of struct hyp_page is only needed when the page is
attached to a free-list, which by definition implies the page is free.
As such, nothing prevents us from using the page itself to store the
list_head, hence reducing the size of the vmemmap.

The hyp buddy allocator currently checks the struct hyp_page list node
to see if a page is available for allocation or not when trying to
coalesce memory. Now that decrementing the refcount and attaching to
the buddy tree is done in the same critical section, we can rely on the
refcount of the buddy page to be in sync, which allows to replace the
list node check by a refcount check. This will ease removing the list
node from struct hyp_page later on.

The hyp_page refcount helpers currently rely on the hyp_pool lock for
serialization. However, this means the refcounts can't be changed from
the buddy allocator core as it already holds the lock, which means pages
have to go through odd transient states.
For example, when a page is freed, its refcount is set to 0, and the
lock is transiently released before the page can be attached to a free
list in the buddy tree. This is currently harmless as the allocator
checks the list node of each page to see if it is available for
allocation or not, but it means the page refcount can't be trusted to
represent the state of the page even if the pool lock is held.
In order to fix this, remove the pool locking from the refcount helpers,
and move all the logic to the buddy allocator. This will simplify the
removal of the list node from struct hyp_page in a later patch.

On Tegra186 and later, the memory controller needs to be programmed in
coordination with any of the ARM SMMU instances to configure the stream
ID used for each memory client.
To support this, add a phandle reference to the memory controller to the
SMMU device tree node.
