ENGR00162491 Android: MX53_SMD: enter recovery mode by key.
Implement a key press check on recovery mode check. User can press Vol- key to enter recovery mode when boot. Idealy, should be a combo key press together, but on SMD it only can Vol+ or Vol- but it can't press together. More usuful for user and less bug.
