The device uses a clock lane, and 1 to 4 DSI data lanes. Let's add the
data-lanes property starting at 1 similar to what the other bridge
bindings are doing.

Let's also drop the data-lanes properties in the example for the DSI host
controller to avoid confusion. The configuration of the DSI host depends
on the controller used and is unrelated to the bridge binding.
