This is ancient cruft that is no longer used, so remove it.

The GCC ARM builds have access to ADRL/LDRL macros that emit relative
symbol references, i.e., references that do not require fixing up at
load time (or FV generation time for XIP modules)
Implement equivalent functionality for RVCT: note that this does not
use movw/movt pairs, but the more compatible add/add/add or add/add/ldr
sequences (which Clang does not support, unfortunately, hence the use
of movw/movt for the GCC toolchain family)

This removes the various Mmio ASM macros that are not used anywhere in
the code, and removes some variants of LoadConstant... () that are not
used anywhere either.
Note that these MmioXxx() implementations are unrelated to the C versions
defined in MdePkg. These are strictly intended for use in assembler, and
no such uses remain.

The SetPrimaryStack and InitializePrimaryStack macros are no longer
used now that we removed support for ArmPlatformGlobalVariableLib.
So remove the various versions of them.

The top of the stack always points to 'stack_base + stack_size'.
But the stack pointer is decremented before writing to the stack.
It means the top byte of the stack is actually 'stack_base + stack_size - 1'.
The initialization should also decrement the stack pointer before
zero'ing the memory (pre-indexed addressing).

Checking if a core if the primary/boot core used to be done with the macro
IS_PRIMARY_CORE().
Some platforms exposes configuration registers to change the primary core.
Replacing the macro IS_PRIMARY_CORE() by ArmPlatformIsPrimaryCore() allows
some flexibility in the way to check the primary core.

The new functions are:
- ArmPlatformStackSet(IN UINTN StackBase, IN UINTN MpId, IN UINTN PrimaryStackSize, IN UINTN SecondaryStackSize);
- ArmPlatformStackSetPrimary(IN UINTN StackBase, IN UINTN MpId, IN UINTN PrimaryStackSize, IN UINTN SecondaryStackSize);

The stack topology can be changed by implementing a new ArmPlatformStackLib

In the previous version, every cores had the same stack size.
To avoid to waste memory with secondary core stacks, the primary core stack
size is now different from the secondary cores stack size.
These are the Stack PCDs and their default values:
gArmPlatformTokenSpaceGuid.PcdCPUCoresSecStackBase|0
gArmPlatformTokenSpaceGuid.PcdCPUCoreSecPrimaryStackSize|0x10000
gArmPlatformTokenSpaceGuid.PcdCPUCoreSecSecondaryStackSize|0x1000

ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers.
EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell.
BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine).
