atomic: Provide atomic_{or,xor,and}
...
Implement atomic logic ops -- atomic_{or,xor,and}.
These will replace the atomic_{set,clear}_mask functions that are
available on some archs.

locking,arch,hexagon: Fold atomic_ops
...
OK, no LoC saved in this case because the !return variants were
defined in terms of the return ops. Still do it because this also
prepares for easy addition of new ops.

arch,hexagon: Convert smp_mb__*()
...
Hexagon uses asm-gemeric/barrier.h and its smp_mb() is barrier().
Therefore we can use the default implementation that uses smp_mb().
