The function ArmPlatformInitializeSystemMemory() is defined by
ArmPlatformLib, but is only ever called when using the PrePeiCore
flavor of the startup code. Also, none of the remaining upstream
platforms actually implement anything in that function in the first
place. So let's just remove it altogether.

The only user of ArmPlatformLib's ArmGetCpuCountPerCluster () is itself
an ArmPlatformLib implementation, i.e., ArmVExpressLibRTSM.
Given that we'd prefer to get rid of ArmPlatformLib entirely, let's
remove ArmGetCpuCountPerCluster () from the API as a first step.

ArmPlatformGetPrimaryCoreMpId returns the MPID of the primary core.
The primary core might not be known at build time (eg: the platform allows
the boot CPU to be changed through board config).
This function is used during the secondary core stack initialization to know
the position of the secondary core in the SoC.
A secondary core that is at the position N, with N greater than the primary
core position, will be at the position N-1 in the list of secondary stacks
(the primary core has its own separate bigger stack).

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.

This change does not make possible to disable Trustzone from the firmware.

On MpCore system, the primary core can now be any core of the system.
To identify the primary core, you can use 'gArmTokenSpaceGuid.PcdArmPrimaryCoreMask'
and 'gArmTokenSpaceGuid.PcdArmPrimaryCore'.
These PCDs by default use the ClusterId and CoreId to identify the core. And the
primary core is defined as the ClusetrId=0 and CoreId=0.
The helper macros are: IS_PRIMARY_CORE(MpId), GET_CORE_ID(MpId), GET_CLUSTER_ID(MpId),
GET_CORE_POS(MpId), PRIMARY_CORE_ID.

The PcdStandalone is a PCD ARM Ltd uses to make the difference between a standalone UEFI (boot
from cold boot to Boot Manager without user intervention) and a Debug UEFI firmware (the firmware
engineer has to copy the Normale World image into the DRAM to enable his/her firmware).
By coping the firmware into DRAM in the non standalone version it is much faster than reflashing
the NOR Flash after each build.
ArmPlatformSecExtraAction() function is called just before the Sec module jump to normal world.
The platform firmware can run extra actions at this stage.
The 'ARM Standalone' concept has moved to the implementation of ArmPlatformSecExtraAction() for
the ARM development boards (in ArmPlatformPkg/Library/DebugSecExtraActionLib).

Some platforms require some of their controllers to be initialized in Secure world.

Formerly, each platform was responsible to declare the location of its UEFI memory
region (used by PEI and DXE Foundations).
The ArmPlatformLib was also declaring every region of its partitionned system memory
with a System Resource HOB.
In this new model, the MemoryInit expects the system memory to be declared with the
PCDs gArmTokenSpaceGuid.PcdSystemMemoryBase/Size.
These PCDs declare the largest continuous DRAM region. Additional regions can be
declared with the ArmPLatformLib function ArmPlatformGetAdditionalSystemMemory().
Now, it is the PEIM that partitions the system memory for every platform. It installs
a region of the size PcdSystemMemoryUefiRegionSize (default 128MB) for the PEI permanent
memory at the top of the DRAM region.
And a region of gArmPlatformTokenSpaceGuid.PcdSystemMemoryFixRegionSize (default 128MB)
is declared at the base of the system memory. This region is used for the allocation that
requires fixed address or have some constraints on their locations.
