Revert "drm/amd/display: Fix overlay validation by considering cursors"

Browse Source 
This reverts commit 33f409e60e.

The patch that we are reverting here was originally applied because it
fixes multiple IGT issues and flickering in Android. However, after a
discussion with Sean Paul and Mark, it looks like that this patch might
cause problems on ChromeOS. For this reason, we decided to revert this
patch.
