  [SRU]alsa-ucm-conf: the volume can't be adjusted on the usb audio of
  the Dell WD15/WD19 dock

Bug description:
  [Impact]
  On the Dell WD15/19 Dock station, there is a USB audio card, and
  a headset audio jack routes to this audio card. We found if we plug
  some specific headset (non-iphone type headset), we could not record
  any sound from headset-mic even we set the input volume to max.

  [Fix]
  Improve the ucm for the audio card in this Dock, let the driver mixer
  value be adjustable, then we could adjust the input volume from driver
  side. 

  [Test Case]
  plug various types of headset to the WD19 and WD15 dock stations, and
  adjust the input volume from gnome, check the input volume in the driver
  by running amixer, found the input volume is changed in the driver;
  record the sound from headset-mic, it could record the sound from all
  headsets we tested.

  [Regression Risk]
  It could make the PA fail to load the ucm on the machines with Dell
  WD15/WD19 dock station, then users only see analogue output/input from
  gnome-control-center instead of usb-speaks usb-lineout and usb-mic.
  But this possibility is very low since we have tested the patch on WD15
  and WD19 dock, all worked very well.
