drm/amd/display: restore code for plane with no modifiers 



When this file was split in commit 5d945cbc ("drm/amd/display:
Create a file dedicated to planes") this chunk seemed to get dropped.

Linus noticed on this rx580 and I've reproduced on FIJI which makes
sense as these are pre-modifier GPUs.

With this applied, I get gdm back.
