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

When this file was split in commit 5d945cb ("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.
