ALSA: hda - Add post_suspend patch ops
Add a new ops, post_suspend(), which is called after suspend() ops is performed. This is called only in the case of the real PM suspend, and the codec driver can use this for further changing of D-state or clearing the LED, etc. Signed-off-by: Takashi Iwai <tiwai@suse.de>
