ArmPlatformPkg/MemoryInitPei: AARCH64 fix memory address calculations
At least for AARCH64 currently, SystemMemoryTop and FdTop can overflow
while adding the 32-bit PCDs together. The resulting value loses the
upper 32-bits. Cast each of the values to EFI_PHYSICAL_ADDRESS size
before doing the addition to prevent erroneous overflow. There is currently
no 32-bit platform in EDKII open source that will overflow and this change
would not fix that problem anyway.
