Revert "drm/amdgpu: rework resume handling for display (v2)"

This reverts commit d897650c which is
commit 73dae652 upstream.

The original patch 73dae652 (drm/amdgpu: rework resume handling for
display (v2)), was only targeted at kernels 6.11 and newer.  It did not
apply cleanly to 6.12 so I backported it and it backport landed as
99a02eab ("drm/amdgpu: rework resume handling for display (v2)"),
however there was a bug in the backport that was subsequently fixed in
063d380c ("drm/amdgpu: fix backport of commit 73dae652").  None
of this was intended for kernels older than 6.11, however the original
backport eventually landed in 6.6, 6.1, and 5.15.

Please revert the change from kernels 6.6, 6.1, and 5.15.
