[meta-rockchip][PATCH 4/4] rauc demo: add

[Trevor Woerner <twoerner@gmail.com>]

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.
