Add an example of implementing rauc on a rockchip board. Adding the meta-rauc layer, adding 'rauc' to DISTRO_FEATURES, and enabling RK_RAUC_DEMO will build an image using the example provided in dynamic-layers/rk-rauc-demo. This example uses a simple A/B + D scheme (i.e. two root partitions and a non-updated /data partition). Repartitioning occurs automatically on first boot thanks to systemd's 'repart' mechanism. NOTE: - this example only works with systemd If you wish to provide your own implementation, simply add the meta-rauc layer, add 'rauc' to DISTRO_FEATURES, don't enable RK_RAUC_DEMO, and provide your own implementation in a separate layer.
