rtc: abx80x: use devm_add_action_or_reset()
If devm_add_action() fails we are explicitly calling the cleanup to free the resources allocated. Lets use the helper devm_add_action_or_reset() and return directly in case of error, as we know that the cleanup function has been already called by the helper if there was any error.
