Michel Dänzer 8e1b45c578 Revert "drm/amd/display: Do not set drr on pipe commit" 
This reverts commit 474f01015f.

Caused a regression:

Samsung Odyssey Neo G9, running at 5120x1440@240/VRR, connected to Navi
21 via DisplayPort, blanks and the GPU hangs while starting the Steam
game Assetto Corsa Competizione (via Proton 7.0).

Example dmesg excerpt:

 amdgpu 0000:0c:00.0: [drm] ERROR [CRTC:82:crtc-0] flip_done timed out
 NMI watchdog: Watchdog detected hard LOCKUP on cpu 6
 [...]
