This change removes the old, deprecated interface from the cs46xx 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 this driver has PCI PM hooks which are set properly.  It also has the
ability to trigger suspend/resume from an ioctl.  This functionality was not
touched, though it could use a serious review if this driver continues to
persist in the mainline tree..

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