Add routing and stream_config support to CAL driver.
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.
CAL doesn't support transcoding, so the driver currently allows changes
only on the camerarx sink side, and then copies the sink pad config to
the source pad. This becomes slighly more complex with 8 source pads and
multiple streams on the sink pad. A helper,
cal_camerarx_get_opposite_stream_format(), is added, which uses the
routing table to get the format from the "opposite" side.
