raspbee on le potato

In short, the gpio pins are the same as on the raspberry pi, so the only thing we need to do is add the correct dt overlay and reboot.

# wget https://raw.githubusercontent.com/libre-computer-project/libretech-overlays/for-4.13.y/overlays/meson-gxl-s905x-libretech-cc-uarta.dts
# armbian-add-overlay meson-gxl-s905x-libretech-cc-uarta.dts
# reboot

The uart will now be available at /dev/ttyAML6

And we just tell zigbee2mqtt which device to use in the docker container.
