drm: Add support for multiple plane types (v2)
The DRM core currently only tracks "overlay"-style planes. Start
refactoring the plane handling to allow other plane types (primary and
cursor) to also be placed on the DRM plane list.
v2: Add drm_for_each_legacy_plane() iterator to smooth transition
of drivers with plane loops.
