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.
