The System Control Processor (SCP) provides access to SoC sensors via the System Control and Power Interface (SCPI) Message Protocol. Add bindings to allow probing of these sensors. Also support referencing of the sensors for setting up thermal zones via the thermal DT bindings.

Gentle ping for the bindings review.
