[PATCH 0/7] drm/amd/display: Drop DRM private objects from amdgpu_dm

[Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>]

Based on the analysis of the bug from [1] the best course of action seems
to be swapping off of DRM private objects back to subclassing DRM atomic
state instead.

This patch series implements this change, but not yet the other changes
suggested in the threads from that bug - these will come later.

CCing dri-devel per Daniel's suggestion since this issue brought
some interesting misuse of private objects.
