[PATCH v4 10/12] ARM: dts: imx7s-warp: add ov2680 sensor node

[Rui Miguel Silva <rui.silva@linaro.org>]

Warp7 comes with a Omnivision OV2680 sensor, add the node here to make complete
the camera data path for this system. Add the needed regulator to the analog
voltage supply, the port and endpoints in mipi_csi node and the pinctrl for the
reset gpio.
