[PATCH v3 1/2] dt-bindings: thermal: amlogic: Add A9 thermal bindings

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao@xxxxxxxxxxx>

Document the thermal controller compatibles for the Amlogic A9 SoC.

Describe the required "core" and "plck" clocks, and update the schema
constraints for A9-specific thermal controllers.
