[PATCH v2 05/19] ARM: dts: imx6-sabresd: add OV5642 and OV5640 camera sensors

Enables the OV5642 parallel-bus sensor, and the OV5640 MIPI CSI-2 sensor.

The OV5642 connects to the parallel-bus mux input port on ipu1_csi0_mux.

The OV5640 connects to the input port on the MIPI CSI-2 receiver on
mipi_csi. It is set to transmit over MIPI virtual channel 1.

Until the OV5652 sensor module compatible with the SabreSD becomes
available for testing, the ov5642 node is currently disabled.

Why is it disabled here?
