Fwiw I think that the idea is good, but I'm wondering on the following
architectural questions:
 - Shouldn't prepared and enabled be part of struct drm_panel ?
 - Would it be better to subclass struct panel_common around struct drm_panel ?

I might be threading the thin line of "midlayer vs helpers" here, so
please let me know if I've got it wrong.

Thanks
