[PATCH 3/6] thermal: Register hwmon in thermal_zone_of_sensor_register_param()

[Marek Vasut <marek.vasut@gmail.com>]

Register hwmon sysfs interface in thermal_zone_of_sensor_register_param()
in case thermal_zone_params->no_hwmon is set to false. This behavior is
the same as thermal_zone_device_register().
