    [OSS] Remove deprecated PM interface from cs4281 driver.

    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.
