Subject: [PATCH v2 01/22] bitops: merge little and big endian definisions in asm-generic/bitops/le.h

In order to make the forthcoming changes smaller, this merges
macro definisions in asm-generic/bitops/le.h for big-endian and
little-endian as much as possible.

This also removes unused BITOP_WORD macro.
