[PATCH 12/15] ARM: dts: imx7: Add video mux, csi and mipi_csi and connections

[Rui Miguel Silva]

This patch adds the device tree nodes for csi, video multiplexer and mipi-csi
besides the graph connecting the necessary endpoints to make the media capture
entities to work in imx7 Warp board.

Also add the pin control related with the mipi_csi in that board.
