Subject: [PATCH 43/51] USB-Audio: Dell-WD15-Dock: make input and output volume
 adjustable

Recently we found the input volume is too low for some specific
headset-mic, even we adjust the input volume to max from PA, we still
can't record the sound from that headset-mic. That is because we
change the input or output volume from PA, but the mixer's volume
is not changed, only PA's soft-volume is changed.

Checking the amixer controls for the sound card in the WD19, it
supports MixerElem, Volume and Switch, and checking the sound card in
the WD15, it doesn't have Volume and Switch for Headphone and Line,
So adding the volume and switch control in the ucm conditionally.
