[RESEND,v4,1/2] dt-bindings: thermal: Add support for Airoha EN7581 thermal sensor

Commit Message

Add support for Airoha EN7581 thermal sensor and monitor. This is a
simple sensor for the CPU or SoC Package that provide thermal sensor and
trip point for hot low and critical condition to fire interrupt and
react on the abnormal state.
