power: power_supply: Add property for ship mode 



In ship mode the charger module opens the bat-fet and disconnects the
battery from the system. This is for the non-removable battery designs
to avoid them from being discharged when shipped/on-shelf.

The ship mode is enabled during the final stage of power-off typically
from the PON driver. Hence, add property POWER_SUPPLY_PROP_SET_SHIP_MODE
to force the device into ship-mode.
