Revert "drm/amdgpu: make display pinning more flexible (v2)"

Browse source 
This reverts commit 6302709784 which is
commit 81d0bcf990 upstream.

This commit causes hiberation regressions on some platforms on kernels
older than 6.1.x (6.1.x and newer kernels works fine) so let's revert it
from 5.15 and older stable kernels.  This should be reverted from 6.0.x
as well, but that kernel is no longer supported.
