Subject: [PATCH v5 12/13] 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.
