[PATCH v3 13/23] ARM: dts: at91: sama7g5: add nodes for video capture

[Eugen Hristev <eugen.hristev@microchip.com>]

Add node for the XISC (eXtended Image Sensor Controller) and CSI2DC
(csi2 demux controller).
These nodes represent the top level of the video capture hardware pipeline
and are directly connected in hardware.

Changes in v3:
- change bus width for endpoints to the default 14
