Bug description:
  [Impact]
  Video output MUX switched from Intel GPU to Nvidia GPU after S3, so
  display settings are lost.
   
  [Fix]
  Always use Nvidia GPU to do the video output. This matches the behavior
  on the other OS.

  [Test]
  Connect and external monitor, and change the scaling factor or
  resolution, suspend the laptop.
  After wakeup, the custom monitor setting is kept.

  [Where problems could occur] 
  If nvidia.ko or nouveau.ko is blacklisted, the video output may stop
  working, as it's now routed away from i915 device.
