power: supply: add inhibit-charge-awake to charge_behaviour



OneXPlayer devices have a charge inhibit feature that allows the user
to select between it being active always or only when the device is on.

Therefore, add attribute inhibit-charge-awake to charge_behaviour to
allow the user to select that charge should be paused only when the
device is awake.
