This change removes the old, deprecated interface from the cs4281 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.

Note that this driver has been obsoleted by an ALSA equivalent.

Note that this driver has hooks for PCI power management, but does not
implement the ->suspend()/->resume() methods.
