Adjust the paired battery policy

Browse source 
1. Disable the charGing and charger input via device tree
configuration
2. Disable charger input if battery is absent or temperature
is too low(<-30 degree C)
3. Force battery to empty to trigger android auto power off
if paired battery becomes empty to avoid it over discharGing.
