make dtbs_check complains about this and says that panel@1 (as well as
#address-cells and #size-cells) are not allowed here. And indeed the
binding for the Toshiba bridge doesn't mention them here.

Do we need this here or should this be moved to the top level to fix
those warnings? I guess what you're doing above is describe a DSI bus
created by the DSI bridge, which also makes sense, so another
alternative would be to fix up the binding and let it accept those
properties.
