The other helpers give you a simple drm pipeline with plane, crtc &
encoder all baked into on drm_simple_pipeline structure. The only thing
variable you have to hook up to that is the drm_connector. And I think for
dead-simple panels avoiding the basic boilerplate in that does indeed make
some sense.
