ALSA: control-led: Integrate mute led trigger
This driver is the only one calling ledtrig_audio_set(), therefore
the LED audio trigger isn't usable standalone. So it makes sense
to fully integrate LED audio triger handling here.
The module aliases ensure that the driver is auto-loaded (if built
as module) if a LED device has one of the two audio triggers as
default trigger.
In addition disable building the old audio mute LED trigger.
