sniper: Keypad support, with recovery and fastboot key combinations
Using the twl4030 keypad allows booting directly into some special boot modes,
such as recovery or fastboot. the VOL+ key will trigger a boot to recovery while
the VOL- key will trigger a boot to fastboot.
The G (gesture) key remains unused at this point.
