verdin-imx8mm: ov5640: add overlay
Add support for the OV5640 camera to the Verdin-iMX8MM. It's worth
noting that in the device tree overlay, there is no pinctrl on the
regulator node because the GPIO for power enable is already configured
in the SOC pinctrl/GPIO controller nodes in the Toradex device tree for
the SOM/Carrier Boards.
