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

This reverts commit 78623b10fc9f8231802536538c85527dc54640a0 which is
commit 81d0bcf9900932633d270d5bc4a54ff599c6ebdb 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.
