drivers/intel/fsp2_0: Enhance portability with uintptr_t/size_t

Replaces fixed-width integers for pointers and sizes with uintptr_t and
size_t, promoting portability across 32-bit and 64-bit architectures.

For FSP-API specific UPD assignments, relying on `efi_uintn_t` rather
fixed size datatype uint32_t/uint64_t.

BUG=b:242829490
TEST=Firmware splash screen visible on google/rex0 w/ both 32-bit and
64-bit compilation.
