HID: i2c-hid: goodix: Use the devm variant of regulator_register_notifier()

In commit 18eeef46 ("HID: i2c-hid: goodix: Tie the reset line to
true state of the regulator") I added a call to
regulator_register_notifier() but no call to unregister. That's a
bug. Let's use the devm variant to handle the unregistering.
