Revert "drm/amdgpu: use dirty framebuffer helper"

Browse Source 
commit 17d819e2828cacca2e4c909044eb9798ed379cd2 upstream.

This reverts commit 66f99628eb24409cb8feb5061f78283c8b65f820.

Unfortunately, that commit causes performance regressions on non-PSR
setups. So, just revert it until FB_DAMAGE_CLIPS support can be added.
