The controller uses a separate D-PHY, which is the same that is otherwise used for MIPI DSI, but used in Rx mode. On the V3s, the CSI0 controller is dedicated to MIPI CSI-2 as it does not have access to any parallel interface pins. Add all the necessary nodes (CSI0, MIPI CSI-2 bridge and D-PHY) to support the MIPI CSI-2 interface. Note that a fwnode graph link is created between CSI0 and MIPI CSI-2 even when no sensor is connected. This will result in a probe failure for the controller as long as no sensor is connected but this is fine since no other interface is available. The interconnects property is used to inherit the proper DMA offset.
