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

This reverts commit 057f47cb609b73eb1dc09f0d398592e2fdc91dd6.

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.
