Subject: [PATCH v1 1/1] bitops: Move aligned_byte_mask() to wordpart.h

The bitops.h is for bit related operations. The aligned_byte_mask()
is about byte (or part of the machine word) operations, for which
we have a separate header, move the mentioned macro to wordpart.h
to consolidate similar operations.
