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.
