thermal: hwmon: EXPORT_SYMBOL_GPL for thermal hwmon sysfs

thermal_add_hwmon_sysfs()/thermal_remove_hwmon_sysfs() need
EXPORT_SYMBOL_GPL(). Otherwise we will have ERROR

>> ERROR: "thermal_remove_hwmon_sysfs" [drivers/thermal/rcar_thermal.ko] undefined!
>> ERROR: "thermal_add_hwmon_sysfs" [drivers/thermal/rcar_thermal.ko] undefined!
