powerpc/align: Use #ifdef __BIG_ENDIAN__ #else for REG_BYTE
Sparse complains that it doesn't know what REG_BYTE is: arch/powerpc/kernel/align.c:313:29: error: undefined identifier 'REG_BYTE' REG_BYTE is defined differently based on whether we're compiling for LE, BE32 or BE64. Sparse apparently doesn't provide __BIG_ENDIAN__ or __LITTLE_ENDIAN__, which means we get no definition. Rather than check for __BIG_ENDIAN__ and then separately for __LITTLE_ENDIAN__, just switch the #ifdef to check for __BIG_ENDIAN__ and then #else we define the little endian version. Technically that's dicey because PDP_ENDIAN is also a possibility, but we already do it in a lot of places so one more hardly matters.
