ArmPkg/ArmPkg.dec: Redefined PcdSystemMemory(Base|Size) as UINT64

Browse Source 
The System Memory region might be out of the 32-bit memory space.

This change has been validated on the FVP AArch64 model using 4GB
of DRAM at 0x8_0000_0000:

-  # System Memory (2GB)
-  gArmTokenSpaceGuid.PcdSystemMemoryBase|0x80000000
-  gArmTokenSpaceGuid.PcdSystemMemorySize|0x80000000
+  # System Memory (4GB)
+  gArmTokenSpaceGuid.PcdSystemMemoryBase|0x800000000
+  gArmTokenSpaceGuid.PcdSystemMemorySize|0x100000000

EFI Shell and Linux kernel boot successfully.

Note: This change has not been validated on AArch32. I expect some
early assembly code to not work.
