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.
