The devres variant of thermal_add_hwmon_sysfs() only takes the thermal
zone structure pointer as parameter.

Actually, it uses the tz->device to add it in the devres list.

It is preferable to use the device registering the thermal zone
instead of the thermal zone device itself. That prevents the driver
accessing the thermal zone structure internals and it is from my POV
more correct regarding how devm_ is used.
