[PATCH] oss: remove deprecated PM interface from maestro driver
This change removes the old, deprecated interface from the maestro 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. The check_suspend() function and associated logic was not removed, even though it is now unnecessary. Note that this driver has been obsoleted by an ALSA equivalent.
