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