rS354723: atomic: Add atomic_cmpset_masked to powerpc and use it

Summary

This is a more optimal way of doing atomic_compset_masked() than the
fallback in sys/_atomic_subword.h. There's also an override for
_atomic_fcmpset_masked_word(), which may or may not be necessary, and is
unused for powerpc.
