Defines two host video capture devices and two camera sensors: parallel-bus OV5642 and MIPI CSI-2 OV5640. One host capture device connects to the OV5642 via the parallel-bus mux input on the ipu1_csi0_mux. The other host capture device connects to the OV5640 via the MIPI CSI-2 receiver (directly on virtual channel 1 to ipu1_csi1 on imx6q, and indirectly via the ipu1_csi1_mux on imx6dl).
