There is no really need to support runtime configuration as of now
since we only support D-PHY, so the delta for v10*should* be tiny,
either a bus-type sanity read in parse_routing(), or even nothing at
DT parse and a future configure() branch when C-PHY lands.

Right, well I tend to agree that a runtime configure() is out of scope, so, I'm going to stick to Rob's guidance.

If you look at other upstream stuff you will see phy-cells = 0 for single mode PHYs and phy-cells = 1 for PHYs that can be in any mode.

Consumer configures the mode in DT like every other upstream MIPI CSI2 PHY.
