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

From: Xianwei Zhao <[email protected]>

Document the thermal controller compatibles for the Amlogic A9 SoC.

Describe the required "core" and "plck" clocks, add the optional
"amlogic,hw-reset-temp" property, and update the schema constraints for
A9-specific thermal controllers.
