thermal_add_hwmon_sysfs()/thermal_remove_hwmon_sysfs() need
EXPORT_SYMBOL(). 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!

EXPORT_SYMBOL_GPL?
That seems to be prevalent in the thermal subsystem, except for a few cases
in cpu_cooling.c and thermal_helpers.c.
