ARM: dts: imx: sabrelite: add video capture ports and endpoints

Defines the host v4l2-capture device node and an OV5642 camera sensor
node on i2c2. The host capture device is a child of ipu1. An OV5642
parallel-bus endpoint is defined that connects to the host parallel-bus
endpoint on CSI0, using the OF graph bindings described in
Documentation/devicetree/bindings/media/video-interfaces.txt.

ARM: dts: imx6-sabresd: add video capture ports and endpoints

Defines the host v4l2-capture device node and two camera sensors:
parallel-bus OV5642 and MIPI CSI-2 OV5640. The host capture device
is a child of ipu1. The MIPI CSI-2 receiver device is also defined.

The OV5642 is connected to the host parallel-bus endpoint on CSI0,
and the OV5640 is connected to the host MIPI CSI-2 endpoint on CSI1,
over virtual channel 0.
