checkpatch: whine about ACCESS_ONCE
Add a test for use of ACCESS_ONCE that could be written using READ_ONCE or
WRITE_ONCE.
--fix it too if desired.
The WRITE_ONCE fixes are less correct than the coccinelle script below as
checkpatch cannot have a completely correct "expression" mechanism because
checkpatch works on patches and not complete files.
$ cat access_once.cocci

- ACCESS_ONCE(e1) = e2
