[ALSA] PM support for cs5535audio
Appended is my patch adding PM support to the cs5535audio driver. I also added the ac97 quirk but it's not yet confirmed which boards need to be in the quirk list. The patch also includes some Kconfig and misc cleanup. Signed-off-by: Jaya Kumar <jayakumar.alsa@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
