[PATCH v4 03/10] hwmon: Use non-OF thermal cooling device registration API

Some HWMON drivers register cooling devices using the OF helper
devm_thermal_of_cooling_device_register() with a NULL device node.

With the introduction of a dedicated non-OF registration API,
switch these users to devm_thermal_cooling_device_register()
to make the intent explicit and avoid relying on OF-specific helpers.

This is a pure refactoring with no functional change.
