[PATCH] oss: remove deprecated PM interface from ad1848 driver

This change removes the old, deprecated interface from the ad1848 driver,
including the pm_{,un}register() calls, the local storage of the pmdev object
and the reference to the old header files.  This change is done to assist in
eradicating the users of the legacy interface so as to help facilitate the
removal of the interface itself.
