This reverts commit 367b3e934f578f6c0d5d8ca5987dc6ac4cd6831d.

While we were testing DCN3.1 with a hub, we noticed that only one of 2
connected displays lights up when using some specific display
resolution. After bisecting this issue, we figured out the commit
mentioned above introduced this issue. We are investigating why this
patch introduced this regression, but we need to revert it for now.
