[PATCH 2/6] hwmon: (aspeed-pwm-tacho) Use devm_thermal_of_cooling_device_register

Use devm_thermal_of_cooling_device_register() to register the cooling
device. As a side effect, this fixes a driver bug:
thermal_cooling_device_unregister() was not called on removal.

Fixes: f198907d2ff6d ("hwmon: (aspeed-pwm-tacho) cooling device support.")
