[PATCH v3 7/9] dt-bindings: sun6i-dsi: Document R40 MIPI-DSI controller (w/ A64 fallback)

[Jagan Teki <jagan@xxxxxxxxxxxxxxxxxxxx>]

The MIPI DSI controller on Allwinner R40 is similar on
the one on A64 like doesn't associate any DSI_SCLK gating.

So, add R40 compatible and append A64 compatible as fallback.
