Subject: [PATCH 2/3] thermal/drivers/thermal_hwmon: Use hwmon_device_register_for_thermal()

The thermal subsystem registers a hwmon device without providing chip
information or sysfs attribute groups. While undesirable, it would be
difficult to change. On the other side, it abuses the
hwmon_device_register_with_info API by not providing that information.
Use new API specifically created for the thermal subsystem instead to
let us enforce the 'chip' parameter for other callers of
hwmon_device_register_with_info().
