ALSA: hda - Add common automute support for mxier-amp on/off for Reatek

Some models do mute on/off the connected mixer widget for the automatic
muting, instead of controlling the pin widget itself.  This patch adds
the implementation of such type of auto-mute in the common helper
function, and reduces the redundant codes for each model preset.
