[PATCH v3 1/2] dt-bindings: arm: rockchip: Add Asus Tinker Board 3/3S

[Michael Opdenacker <michael.opdenacker@rootcommit.com>]

Document the compatible strings for Asus Tinker Board 3 [1] and 3S [2],
which are SBCs based on the Rockchip 3566 SoC.

The "3S" version ("S" for "storage") just adds a 16 GB eMMC
and a "mask ROM" DIP switch to the "3" version.
