Subject: [PATCH 3/4] power: supply: mm8013: implement
 POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR_AVAILABLE

The sysfs is documented to report both the current and all available
behaviours. For this POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR_AVAILABLE needs
to be implemented.

Note that this changes the format of the sysfs file
(to the documented format):

Before: "auto"
After:  "[auto] inhibit-charge"
