No platforms use the ARMv6 (ARM11) support code anymore. In fact, the
only reference to it in ArmPkg.dsc was commented out by Andrew in SVN
r11298 (2011-02-03) so it may well be broken. So remove it.

Instead of inferring the GIC revision from the CPU id registers
and the presence/availability of the system register interface
upon each invocation, move the logic to a constructor and cache
the result.

The current implementation of ArmGicGetSupportedArchRevision ()
that is used by all ARM platforms is entirely stateless (in order
to support being executed from flash) so it needs to interrogate
the hardware for the supported GIC revision upon each invocation.
However, this statelessness is only needed for SEC type modules;
in all other cases, we could easily determine the GIC revision once,
and store the result in a global variable.
In preparation of having separate early and normal versions, this patch
introduces the ArmGicArchLib library class and default implementation,
and moves the existing ArmGicGetSupportedArchRevision () into it.

This removes the range size threshold for virtual address based cache
maintenance instructions that operate on VA ranges to be 'promoted' to
use set/way instructions.
Doing so is unsafe: set/way operations are fundamentally different
from VA operations, and really only suitable for cleaning or invalidating
a cache when turning it on or off.
To quote the ARM ARM (DDI0487A_d G3.4):
"""
Since the set/way instructions are performed only locally, there is no
guarantee of the atomicity of cache maintenance between different PEs,
even if those different PEs are each performing the same cache maintenance
instructions at the same time. Since any cacheable line can be allocated
into the cache at any time, it is possible for [a] cache line to migrate
from an entry in the cache of one PE to the cache of a different PE in a
manner that the cache line avoids being affected by set/way based cache
maintenance. Therefore, ARM strongly discourages the use of set/way
instructions to manage coherency in coherent systems.

Example: With MicroSeconds = 200 us, PcdArmArchTimerFreqInHz = 24MHz.
200*24000000 = 0x1_1E1A_3000 => So 0x1E1A_3000 when the type is UINT32.

This changes the definition and a bunch of references to
gArmTokenSpaceGuid.PcdSystemMemoryBase and
gArmTokenSpaceGuid.PcdSystemMemorySize so they can be declared as dynamic PCDs
by the platform. Also, move the non-SEC call to
ArmPlatformInitializeSystemMemory() earlier, so a platform has a chance to set
these PCDs before they are first referenced.
The purpose is allowing dynamically instantiated virtual machines to declare

The ArmArchTimerLib.h include file is not directly related to the TimerLib
instance ArmArchTimerLib, so the name is confusing. Rename to ArmArchTimer.h
instead.

Allow the PCDs gArmTokenSpaceGuid.PcdGicDistributorBase and
gArmTokenSpaceGuid.PcdGicInterruptInterfaceBase to be redeclared
as PcdsDynamic by the platform, so virtual machines can set these
properties during boot. As the PcdGet32() calls now call into the
PCD database, cache the values that are required during the handling
of interrupts.

- Fix ARM Thumb mask operator. This was flagged by a toolchain as warning
"use of logical '&&' with constant operand [-Wconstant-logical-operand]"
- AArch64 should not be building the ARM32 disassemblers.
- Add a AArch64 build target. The disassembler is still to be
implemented.

It is actually the same sequence as AArch64.
Without cleaning the data cache prior to disable the cache, the LR value
pushed on the stack when entering in ArmCleanInvalidateDataCache()
might have been overwritten by this specific cache line maintenance.

Prior to this change the frequency was rounded to 1Mhz.
This change rounds the timer frequency to 1KHz.
