ALSA: hda - Fix S3/S4 problem on machines with VREF-pin mute-LED

commit 88d686027bb43f585914c77dd363f6e817b42c2a upstream.

The verb command in stac92xx_post_suspend caused the audio to stop
working after resuming from S3 mode on HP laptops with the VREF-pin
mute-LED control.  Removing relevant post_suspend registering.

Although removing D3 on AFG is no optimal solution, the impact should
be small in comparison with the broken S3/S4.
