Subject: [RFC PATCH 11/26] thermal: intel: soc_dts_iosf: Migrate to thermal_zone_device_register()

The thermal API has a new thermal_zone_device_register() function which
is deprecating the older thermal_zone_device_register_with_trips() and
thermal_tripless_zone_device_register().

Migrate to the new thermal zone device registration function.
