I changed the thermal.txt in the patch 3/4, to move these two properties
to optional property.
On the Dalmore, we just need to register these two sensors as thermal
zone devices.
Indeed, we have a skin-temperature driver, which used these two thermal
zone deives' temperature to estimator the skin temperature, so we
doesn't need to set trips and bind with any cooling devices on them.
Thanks.
