Bug description:
[Impact]
When TBT monitor is connected to AMD platform, system resume will hit
stack corruption or BUG_ON() macro.
[Fix]
Revert the offending commit and handle MST properly.
[Test]
The system can resume normally and no more kernel splat.
[Where problems could occur]
The new logic is restriced to MST hub, so normal DP/HDMI usage should be
unaffected.
