We can now probe devices with ti-sysc interconnect driver and dts data.
Let's drop the related platform data and custom ti,hwmods dts property.
As we're just dropping data, and the early platform data init is based on
the custom ti,hwmods property, we want to drop both the platform data and
ti,hwmods property in a single patch.

Let's configure omap4 l3 for power-domain and clocks in preparation for
starting to use simple-pm-bus. We will flip over to using simple-pm-bus
later on after dropping the legacy data for all the devices on l3
interconnect.

In preparation for probing l3 with simple-pm-bus and genpd, we must move
l3 noc to a separate node. This is to prevent omap_l3_noc.c driver from
claiming the whole l3 instance before simple-pm-bus has a chance to probe.

We need mmio-sram early for omap4_sram_init() for IO barrier init, and
will be moving l3 interconnect to probe with simple-pm-bus that probes
at module_init() time. So let's move mmio-sram out of l3 to prepare for
that.
Otherwise we will get the following after probing the interconnects with
simple-pm-bus:
omap4_sram_init:Unable to get sram pool needed to handle errata I688

Note that the old sysc register offset is wrong, the real offset is at
0x1100 as listed in TRM for SATA_SYSCONFIG register. Looks like we've been
happily using sata on the bootloader configured sysconfig register and
nobody noticed. Also the old register range for SATAMAC_wrapper registers
is wrong at 7 while it should be 8. But that too seems harmless.
There is also an L3 parent interconnect range that we don't seem to be
using. That can be added as needed later on.

In order to update pcie to probe with ti-sysc and genpd, let's update the
pcie ranges to not use address 0 for 0x20000000 and 0x30000000. The range
for 0 is typically used for child devices as the offset from the module
base. In the following patches, we will update pcie to probe with ti-sysc,
and the patches become a bit confusing to read compared to other similar
modules unless we update the ranges first. So let's just use the full
addresses for ranges for the 0x20000000 and 0x30000000 ranges.

As upstream Linux does not support XIP (eXecute-In-Place) for ARMv7-A
platforms that are part of the ARCH_MULTIPLATFORM framework, it cannot
run in the 8 MiB of HyperRAM present on the RZ/A2M CPU board. Hence the
64 MiB of SDRAM on the sub-board needs to be enabled, which has the
following ramifications:
- SCIF4 connected to the on-board USB-serial can no longer be used as
the serial console,
- Instead, SCIF2 is used as the serial console, by connecting a 3.3V
TTL USB-to-Serial adapter to the CMOS camera connector,
- The first Ethernet channel can no longer be used,
- USB Channel 1 loses the overcurrent input signal.
Based on the Linux-4.19 BSP for RZ/A2.

The LLVM ld.lld linker uses a different symbol type for __bss_start,
resulting in the calculation of KBSS_SZ to be thrown off. Up until now,
this has gone unnoticed as it only affects the appended DTB case, but
pending changes for ARM in the way the decompressed kernel is cleaned
from the caches has uncovered this problem.
On a ld.lld build:
$ nm vmlinux |grep bss_
c1c22034 D __bss_start
c1c86e98 B __bss_stop
resulting in
$ readelf -s arch/arm/boot/compressed/vmlinux | grep bss_size
433: c1c86e98 0 NOTYPE GLOBAL DEFAULT ABS _kernel_bss_size
which is obviously incorrect, and may cause the cache clean to access
unmapped memory, or cause the size calculation to wrap, resulting in no
cache clean to be performed at all.
Fix this by updating the sed regex to take D type symbols into account.

After set PROBE_PREFER_ASYNCHRONOUS flag on the mmc host drivers,
the order of /dev/mmcblkN was not fixed in some SoCs which have
multiple SDHI and/or MMCIF controllers. So, we were hard to use
such a device as rootfs by using the kernel parameter like
"root=/dev/mmcblkNpM".
According to the discussion on a mainling list [1], we can add
mmc aliases to fix the issue. So, add such aliases into R-Car Gen2
board dts files. Note that, since R-Car Gen2 is even more complicated
about SDHI and/or MMCIF channels variations and they share pins,
add the aliases into board dts files instead of SoC dtsi files.
