thermal: intel: intel_soc_dts_iosf: Pass sensors to update_trip_temp()

After previous changes, update_trip_temp() only uses its dts argument to
get to the sensors field in the struct intel_soc_dts_sensor_entry object
pointed to by that argument, so pass the value of that field directly to
it instead.

No intentional functional impact.
