Add compulsory device tree support to the Cirrus ep93xx ARMv4 platform.
- select PINCTRL_EP93xx
- select COMMON_CLK_EP93XX, as clock driver moved out of platform code
- select ARCH_HAS_RESET_CONTROLLER
Select ARM_ATAG_DTB_COMPAT to update device tree with information
about memory passed from bootloader.
We have to leave all MACH options as they are used for board checking
before decomp, to turn off watchdog and ethernet DMA.

Prepare ep93xx SOC gpio to convert into device tree driver:
- dropped banks and legacy defines
- split AB IRQ and make it shared
We are relying on IRQ number information A, B ports have single shared
IRQ, while F port have dedicated IRQ for each line.
Also we had to split single ep93xx platform_device into multiple, one
for each port, without this we can't do a full working transition from
legacy platform code into device tree capable. All GPIO_LOOKUP were
change to match new chip namings.

Nam Cao <namcao@linutronix.de> says:
Hi,
For XIP kernel, the writable data section is always at offset specified in
XIP_OFFSET, which is hard-coded to 32MB.
Unfortunately, this means the read-only section (placed before the
writable section) is restricted in size. This causes build failure if the
kernel gets too large.
This series remove the use of XIP_OFFSET one by one, then remove this
macro entirely at the end, with the goal of lifting this size restriction.
Also some cleanup and documentation along the way.
* b4-shazam-merge
riscv: remove limit on the size of read-only section for XIP kernel
riscv: drop the use of XIP_OFFSET in create_kernel_page_table()
riscv: drop the use of XIP_OFFSET in kernel_mapping_va_to_pa()
riscv: drop the use of XIP_OFFSET in XIP_FIXUP_FLASH_OFFSET

XIP_OFFSET is the hard-coded offset of writable data section within the
kernel.
By hard-coding this value, the read-only section of the kernel (which is
placed before the writable data section) is restricted in size. This causes
build failures if the kernel gets too big [1].
Remove this limit.

On XIP kernel, the name "va_kernel_pa_offset" is misleading: unlike
"normal" kernel, it is not the virtual-physical address offset of kernel
mapping, it is the offset of kernel mapping's first virtual address to
first physical address in DRAM, which is not meaningful because the
kernel's first physical address is not in DRAM.
For XIP kernel, there are 2 different offsets because the read-only part of
the kernel resides in ROM while the rest is in RAM. The offset to ROM is in
kernel_map.va_kernel_xip_pa_offset, while the offset to RAM is not stored
anywhere: it is calculated on-the-fly.
Remove this confusing "va_kernel_pa_offset" and add
"va_kernel_xip_data_pa_offset" as its replacement. This new variable is the
offset of virtual mapping of the kernel's data portion to the corresponding
physical addresses.
With the introduction of this new variable, also rename
va_kernel_xip_pa_offset -> va_kernel_xip_text_pa_offset to make it clear
that this one is about the .text section.

The crash utility uses va_kernel_pa_offset to translate virtual addresses.
This is incorrect in the case of XIP kernel, because va_kernel_pa_offset is
not the virtual-physical address offset (yes, the name is misleading; this
variable will be removed for XIP in a following commit).
Stop exporting this variable for XIP kernel. The replacement is to be
determined, note it as a TODO for now.

The XIP_FIXUP macro is used to fix addresses early during boot before MMU:
generated code "thinks" the data section is in ROM while it is actually in
RAM. So this macro corrects the addresses in the data section.
This macro determines if the address needs to be fixed by checking if it is
within the range starting from ROM address up to the size of (2 *
XIP_OFFSET).
This means if the kernel size is bigger than (2 * XIP_OFFSET), some
addresses would not be fixed up.
XIP kernel can still work if the above scenario does not happen. But this
macro is obviously incorrect.
Rewrite this macro to only fix up addresses within the data section.

bo_meminfo() wants to inspect bo state like tt and the ttm resource,
however this state can change at any point leading to stuff like NPD and
UAF, if the bo lock is not held. Grab the bo lock when calling
bo_meminfo(), ensuring we drop any spinlocks first. In the case of
object_idr we now also need to hold a ref.

There is a real deadlock as well as sleeping in atomic() bug in here, if
the bo put happens to be the last ref, since bo destruction wants to
grab the same spinlock and sleeping locks. Fix that by dropping the ref
using xe_bo_put_deferred(), and moving the final commit outside of the
lock. Dropping the lock around the put is tricky since the bo can go
out of scope and delete itself from the list, making it difficult to
navigate to the next list entry.
