Clean up to update the reference of the these macros: EFI_SIGNATURE_16 -> SIGNATURE_16 EFI_SIGNATURE_32 -> SIGNATURE_32 EFI_SIGNATURE_64 -> SIGNATURE_64 EFI_FIELD_OFFSET -> OFFSET_OF EFI_MAX_BIT -> MAX_BIT EFI_MAX_ADDRESS -> MAX_ADDRESS These macros are not defined in UEFI spec. It makes more sense to use the equivalent macros in Base.h to avoid alias.
