[edk2-devel][PATCH 1/5] IntelFsp2Pkg: X64 compatible changes to support PEI in 64bit

["Kuo, Ted" <ted.kuo@intel.com>]

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3893
1.Added EFIAPI to FspNotifyPhasePeimEntryPoint.
2.Changed AsmReadEsp to AsmReadStackPointer.
3.Changed the type of the return value of AsmReadStackPointer
  from UINT32 to UINTN.
4.Changed the type of TemporaryMemoryBase, PermenentMemoryBase
  and BootLoaderStack from UINT32 to UINTN.
5.Some type casting to pointers are UINT32. Changed them to
  UINTN to accommodate both IA32 and X64.
6.Corrected some typos.
