Add timeout to infinite loops during the CPU powerup procedures. It
is better to report an error instead of busylooping for infinite time
in case of failure.

%pF and %pf are functionally equivalent to %pS and %ps conversion
specifiers. The former are deprecated, therefore switch the current users
to use the preferred variant.
The changes have been produced by the following command:
git grep -l '%p[fF]' | grep -v '^\(tools\|Documentation\)/' | \
while read i; do perl -i -pe 's/%pf/%ps/g; s/%pF/%pS/g;' $i; done
And verifying the result.

ARM64 standard pgtable functions are going to use pgtable_page_[ctor|dtor]
or pgtable_pmd_page_[ctor|dtor] constructs. At present KVM guest stage-2
PUD|PMD|PTE level page tabe pages are allocated with __get_free_page()
via mmu_memory_cache_alloc() but released with standard pud|pmd_free() or
pte_free_kernel(). These will fail once they start calling into pgtable_
[pmd]_page_dtor() for pages which never originally went through respective
constructor functions. Hence convert all stage-2 page table page release
functions to call buddy directly while freeing pages.

I2C2 is available on the PE pingroup, on the same pins as the camera
sensor interface (CSI) controller's camera control interface pins.
This provides an option to use I2C2 instead of that control interface
to configure camera sensors.
Add a pinctrl node for it. The property /omit-if-no-ref/ is added to
keep the device tree blob size down if it is unused.

gpio tracing was made configurable in 4.4-rc1 (commit ddd70280bf0e
("tracing: gpio: Add Kconfig option for enabling/disabling trace
events")). Since then it is the only event type that can be compiled
conditionally. Given that there is only little overhead I don't
understand the reasoning and I was annoyed more than once that gpio
events were not available without recompiling.
So drop the Kconfig symbol and make gpio events available
unconditionally.

In the current state, A33 NAND controllers use PIO during
transfers. Throughput can be increased thanks to the use of DMA
(mostly during reads, because of the ECC pipelining feature).
Besides the usual addition of DMA DT properties, because the A33
NAND DMA handling is different than for older SoCs, we must also
update the compatible which has recently been introduced for this
purpose.

Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit
architectures. These types are required to support block device and/or
file sizes larger than 2 TiB, and have generally defaulted to on for
a long time. Enabling the option only increases the i386 tinyconfig
size by 145 bytes, and many data structures already always use
64-bit values for their in-core and on-disk data structures anyway,
so there should not be a large change in dynamic memory usage either.
Dropping this option removes a somewhat weird non-default config that
has cause various bugs or compiler warnings when actually used.

In preparation of dropping interconnect target module platform data in
