Add multiplexed streams support. CAL has 8 dma-engines and can capture 8 separate streams at the same time. Add 8 video device nodes, each representing a single dma-engine, and set the number of source pads on camerarx to 8. Each video node can be connected to any of the source pads on either of the camerarx instances using media links. Camerarx internal routing is used to route the incoming CSI-2 streams to one of the 8 source pads.
