ARM GICv3 specification introduces some new components and registers.
This patch adds their definitions.
The most important GICv3 component is the GIC Redistributor. It supports
LPIs (Locality-specific peripheral Interrupt), 8+ CPU configuration.
Some GIC distributor registers have moved to the GIC redistributor.

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).

The SMC helper functions were buggy as they were assuming that
the values in x1-x7 registers were preserved across an SMC call,
which is not the case. This patch fixes this issue.
It also simplifies the code by providing only 1 version of the SMC
helper function. We used to have 4 versions depending on the number
of arguments. The problem with this approach was that the number of
arguments also dictated the number of return values, which is
completely unrelated. E.g. you can have an SMC call that takes
1 argument but returns 4 values.

The idea is to keep ArmPkg responsible for the ARM architectural modules and ArmPlatformPkg
the ARM development platform packages (with their respective drivers).
ArmPlatformPkg: Reduce driver dependency on ArmPlatform.h
- Move some driver definitions from C-Macro to PCD values
- Unify PCD driver namespace

The errors were:
- uncaught returned error
- used of uninitialized variables
ArmPlatformPkg/Bds: Implement the update of MemMap Boot Device

The previous version was using the string representation of the Device Path.
This new version takes as paramater the binary representation of the Device Path
It also tries to detect which kind of device support it refers by using the remaining
part of the Device Path after it has been loaded by gBS->ConnectController()
Lots of bug have been fixed as well in this new version.

This implementation use the Tpidrurw software context register to
store the PEI Services Table Pointer.
The author of this patch is Eugene Cohen (HP).

These functions set/clear the SCTLR.V bit that controls the location
of the Vector Table.
This commit also forces the SCTLR.V to be clear when the VBAR register
is set.
Note: The original fix has been proposed by Eugene Cohen (HP).

- There were some missing and duplicate files in ArmPkg.dsc
- PL301Axi.h was missing to build ArmVExpress-CTA9x4 build
Note: PL34xDmc has been temporary removed from ArmPkg just
the time to fix its dependency on ArmPlatform.h

Formerly, it was only possible to use section size granularity for the
translation table regions.
This change allows to define initial translation table regions with
4K-byte granularty (page size granularity).

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).
