Revert "drm/amd/display: Refactor and add visual confirm for HW Flip Queue"

This reverts commit 3ca402375a2197579d1029e7fa9d856847fe0e7b.

Recent visual confirm changes are regressing the driver, causing a
black screen on boot in some green sardine configs, or visual confirm
is not updated at all.
