MIPI CSI-2 is supported on the A83T with a dedicated controller that
covers both the protocol and D-PHY. It can be connected to the CSI
interface as a V4L2 subdev through the fwnode graph.

This is not done by default since connecting the bridge without a
subdev attached to it will cause a failure on the CSI driver.
