Bug description:
  == SRU Justification ==
  [Impact]
  On P620, only single port can work on rear panel. For example, when the 
Line-Out is plugged, the Mic won't work anymore.

  [Fix]
  Use upstream version of UCM to handle port priority correctly, instead of 
separate ports into different profiles.

  [Test]
  Once the UCM is in place, all three ports of rear panel work correctly.

  [Where problems could occur]
  UCM is not a static thing - it's actually interpreted differently at higher 
level. So any change in userspace daemons other than PulseAudio may not like 
the change and can interpret the UCM in another way.

  == Original Bug Report ==
  After backporting following patches from PA and alsa-ucm-conf and then it 
works.

  Since the upstream not yet accepted those patches, the regression
  potential may quite high.
