For a combined CSI/DSI PHY that's a good model, and it re-establishes
the principle that the consumer chooses the mode.

For our simpler camera-only case the cell has less work to do. The
series carries #phy-cells = 1 per Rob's feedback and an RB from Krzysztof.

That's reviewed, tested and mergeable.

The one alternative under discussion with Vinod is bus-type in the CSID 
controller's endpoint with the mode conveyed via phy_configure(). Either 
way the consumer decides.
