[PATCH 3/4] dt-bindings: arm: rockchip: Add Radxa ROCK 3B

[Jonas Karlman]

Add devicetree binding documentation for the Radxa ROCK 3B board.

The Radxa ROCK 3B is a single-board computer based on the Pico-ITX form
factor (100mm x 75mm). Two versions of the ROCK 3B exists, a community
version based on the RK3568 SoC and an industrial version based on the
RK3568J SoC.
