ALSA: hda - Add "Mute-LED Mode" enum control
Create snd_hda_add_vmaster_hook() and snd_hda_sync_vmaster_hook()
helper functions to handle the mute-LED in vmaster hook more
commonly. In the former function, a new enum control "Mute-LED Mode"
is added. This provides user to choose whether the mute-LED should be
turned on/off explicitly or to follow the master-mute status.
