I've gone back and forth on it. I think we need to express what
properties from the common properties apply for a particular panel.
I've been requiring panel bindings to be explicit here rather than
just say "uses the simple-panel binding." For example, if
'power-supply' is not listed, does the panel have a single supply or
multiple supplies that haven't haven't been considered?
