Any reason for reverting this instead of looking into "amdgpu_dm_setup_replay()" and
"replay_feature_enabled" to see why reply is being enabled?

This reverts commit a92da5bc33ea99a861f6c422192af6072c145d2d. V2: Reword commit message [WHY] This commit caused regression in which eDP's with PSR support, but no Replay support (Sink support <= 0x03), failed enabling PSR and all IGT amd_psr tests. [HOW] Reverted the patch.
