This change will allow the pipeline handler to enumerate and control Video Mux or Bridge devices that may be attached between sensors and a particular Unicam instance. Cascaded mux or bridge devices are also handled. A new member function RPiCameraData::enumerateVideoDevices(), called from PipelineHandlerRPi::registerCamera(), is used to identify and open all mux and bridge subdevices present in the sensor -> Unicam link. Relevant links are enabled/disabled and pad formats correctly set in PipelineHandlerRPi::configure() before the camera is started.
