edk2 is removing support for ARM32, so drop all
ARM32 code from edk2-platforms. This does not
change code copied from edk2 as-is.

edk2 PR https://github.com/tianocore/edk2/pull/6048 moves
AsmMacroIoLib.h and AsmMacroIoLibV8.h to MdePkg and renames
them to Arm/AsmMacroLib.h and AArch64/AsmMacroLib.h, respectively.
This updates all edk2-platforms in one go, as this is a breaking
change and no functional change.

RunAxf is a shell command used for running an Axf file. The
ShellDynCmdRunAxfHandler() loads an ELF file or one processed by the
Flashloader. It calls the appropriate loaders to load the file in
memory and to obtain the entry point address.
The first argument to RunAxfPivot() is the entry point address for the image
to execute. The patch
https://github.com/tianocore/edk2-platforms/commit/996047695a06167a918b07b22fcd0fbd0def5da6
changes set/way cache maintenance operations to by-VA operation. This patch
however introduced an error: 'variable StartElf is not initialized'.
Since, StartElf is the first argument to RunAxfPivot(), which is expected to
be the entry point address; RunAxfPivot() would end up branching to an
invalid address resulting in a crash.
Therefore, initialize StartElf to the entry point address before calling
RunAxfPivot().

Currently, the 'runaxf' shell command that exists only on ARM's own
development platforms deals with the caches in an unsafe manner, as
it relies on set/way maintenance to ensure that the ELF image it has
put into memory, as well as the running image itself is visible in
memory after the MMU and caches are disabled.
So let's switch to by-VA maintenance for the currently running image,
as well as the ELF image, and use a helper in assembly to ensure that
we are not relying on the stack between the disabling of the MMU and
the invocation of the ELF image.

BootMonFs and ArmShellCmdRunAxf are only used on development boards
manufactured by ARM itself, so let's keep it under Platform/ARM where
it belongs.
