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.
