For new panels we today requires:
- connector_type
- bus_flags
- bus_format
(Assuming this is a DPI connector panel).
We are working on a patch that wll warn for panels missing required
info. Today a lot of panels are missing info so it is easy to find
panels that does not include all relevant info.
