efi: Set EFIAPI to 32-bit ABI for FSP1_1

Because PLATFORM_USES_FSP2_X86_32 default to false when
PLATFORM_USES_FSP1_1, efi_datatype.h wrongly defines EFI as
__attribute__((__ms_abi__)).

TEST=When some code involved in the build of a platform using
     FSP 1.1 such as Google/CYAN includes efi_datatype.h, it does
     not hit the following error: '__ms_abi__' calling convention
     is not supported for this target
