ALSA: hda: generic: Add vmaster mute LED helper
Like mic-mute LED handling, add a new helper to deal with the master
mute LED with LED classdev. Unlike the mic-mute case, the playback
master mute is hooked on vmaster, and we suppose no nested hooks
allowed there.
The classdev creation code is factored out to a common function that
is called from both mute and mic-mute LED helpers.
