thermal: thermal_hwmon: Convert to hwmon_device_register_with_info()
Booting Linux on a mx6q based board leads to the following warning:
(NULL device *): hwmon_device_register() is deprecated. Please convert the
driver to use hwmon_device_register_with_info().
,so do as suggested.
Also, this results in the core taking care of creating the 'name'
attribute, so drop the code doing that from the thermal driver.
