Revert "thermal: thermal_hwmon: Convert to hwmon_device_register_with_info()"
This reverts commit 7611fb68062f ("thermal: thermal_hwmon: Convert to
hwmon_device_register_with_info()").
Pavel Machek reported breakage in the Nokia N900 due to this commit.
We can revisit a proper fix for the warning later.
