Bug description:
[Impact]
When Type-C DP/HDMI is in use, s0ix resume renders both eDP and DP
outputs blank.
[Fix]
Query the firmware to ensure the DP alt status.
[Test]
Suspend and resume the system, both eDP and Type-C DP/HDMI are working.
[Where problems could occur]
This fix only applies to certain AMD GFX with certain firmware version,
so the scope is very limited.
