[ALSA] hda-codec - make volume knob, the master volume for sigmatel codecs
VolumeKnob is present on most sigmatel codecs, it allows to decrease volume of all DACs at once, it is a kind of post-procesing volume. Note that all output amps of sigmatel only decrease volume, and all input amps only increase volume.
