arm64: dts: imx8mm-venice-gw72xx-0x: add dt overlay for imx219 rpi v2 camera 

Add support for the RaspberryPi Camera v2 which is an IMX219 8MP module:
 - https://datasheets.raspberrypi.com/camera/camera-v2-schematics.pdf
 - has its own on-board 24MHz osc so no clock required from baseboard
 - pin 11 enables 1.8V and 2.8V LDO which is connected to
   GW73xx MIPI_GPIO4 (IMX8MM GPIO1_IO1) so we use this as a gpio

Support is added via a device-tree overlay.

The IMX219 supports RAW8/RAW10 image formats.
