[OSS] Remove deprecated PM interface from maestrodriver.
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.
