Blackfin: bf533: merge fio_flag back into normal mach headers
We don't want the BF533 to be different in terms of its MMR headers, so
merge the FIO_FLAG helpers back into the normal place. To avoid circular
dependencies with headers, turn the inline C funcs into CPP defines. Not
like there will be any code size differences.
