V4L2_SUBDEV_ROUTING_NO_STREAM_MIX routing validation flag means that all routes from a sink pad must go to the same source pad and all routes going to the same source pad must originate from the same sink pad. This does not cover all use cases. For example, if a device routes all streams from a single sink pad to any of the source pads, but streams from multiple sink pads can go to the same source pad, the current flag is too restrictive. Split the flag into two parts, V4L2_SUBDEV_ROUTING_NO_SINK_STREAM_MIX and V4L2_SUBDEV_ROUTING_NO_SOURCE_STREAM_MIX, which add the restriction only on one side of the device. Together they mean the same as V4L2_SUBDEV_ROUTING_NO_STREAM_MIX.
