[PATCH v2 2/4] media: imx.rst: Provide an example for unprocessed video capture

[Fabio Estevam <festevam@gmail.com>]

The current example for imx6q-sabresd is for a direct conversion pipeline.

Provide an extra example using unprocessed video capture for completeness.

 The OV5640 module connects to MIPI connector J5 (sorry I don't have the
 compatible module part number or URL).
 
+The following example configures unprocessed video capture pipeline to
+capture from the OV5640, transmitting on MIPI CSI-2 virtual channel 0:

 The following example configures a direct conversion pipeline to capture
 from the OV5640, transmitting on MIPI CSI-2 virtual channel 0. It also
 shows colorspace conversion and scaling at IC output.
