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.
