[PATCH 4/4] powerpc/sparse: Use LE definition of REG_BYTE

[Daniel Axtens]

Sparse complains that it doesn't know what REG_BYTE is:

arch/powerpc/kernel/align.c:313:29: error: undefined identifier 'REG_BYTE'
arch/powerpc/kernel/align.c:320:37: error: undefined identifier 'REG_BYTE'
arch/powerpc/kernel/align.c:328:29: error: cast from unknown type
arch/powerpc/kernel/align.c:328:29: error: cast from unknown type

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__, so add an explicit __CHECKER__ to the LE
definition.

The choice of LE is arbitrary.
