[Freedreno] [PATCH 00/11] drm/msm/dpu: cleanup plane state

[Dmitry Baryshkov]

This is a cleanup part of the DPU multirect patchset [1], split away to
ease review and merging per Abhinav's request.

Currently significant part of atomic plane state is stored in the
drm_plane's subclass rather than drm_plane_state's subclass. Move it
either to the drm_plane_state or even to the on-stack allocation.
