locking/atomic: Add kernel-doc and docbook_oldnew variables for headers
The andnot, dec, inc, and try_cmpxchg files in the scripts/atomic/fallbacks
directory do not supply kernel-doc headers. One reason for this is that
there is currently no reasonably way to document either the ordering or
whether the old or the new value is returned.
Therefore, supply docbook_order and docbook_oldnew sh variables that contain
the needed information.
