Soliciting DRM feedback on latest DC rework

while this looks more and more like it could work something which would
really help would be to have a set of patches squashed together and
rebased on drm-next.
The dc-drm-next-atomic-wip looks like a start, but we need more
drm/amdgpu: add base DC components
drm/amdgpu: add DCE8 support for DC
drm/amdgpu: add DCE9 support for DC
drm/amdgpu: add DCE10 support for DC
drm/amdgpu: enable DC globally
drm/amdgpu: remove old display infrastructure
Otherwise I fear that people will just be lost in the mass amount of
patches we have in the branch.
