pmic: Enable Low Battery Shutdown for 2.8V

There's an increasing ammount of users that kill their batteries when forgetting their devices into AutoRCM / RCM mode.

This will now force a shutdown the moment the battery reaches 2.8V. Even if device is inside RCM mode.

Notice: We might need to increase the limit.
