drm/mediatek: Remove mtk_drm_plane
...
Now that mtk_drm_plane just contains its base struct drm_plane, we can
just remove it and use struct drm_plane everywhere.

drm/mediatek: plane: Remove plane zpos/index
...
It is not actually useful to a mtk plane to know its zpos/index, so just
remove this field.
This let's completely remove struct mtk_drm_plane in a follow up patch.

drm: Drop crtc argument from __drm_atomic_helper_crtc_destroy_state
...
It's unused, and really this helper should only look at the state
structure and nothing else.
v2: Rebase on top of rockchip changes
v3: Drop unrelated hunk, spotted by Laurent.
v4: Rebase onto mtk driver merge.
