Provide the two MIPI DSI encoders on the V3U and connect them to the DU
accordingly.

I'm not sure if EXTAL is the right clock, the datasheet isn't clear
about this. It's a guess as good as any other of the possible options,
so we could start with it and possibly fix it later, but could you try
to get clarification from Renesas on this ?
