-Required properties :

-   adapter is either plugged in or removed.

-   status. This is a Host GPIO that is configured as an input and connected
-   to the ACOK pin on the bq24735. Note: for backwards compatibility reasons,
-   the GPIO must be active on AC adapter absence despite ACOK being active
