Subject: [PATCH v2 4/8] power: ab8500: Use power_supply_*() API for accessing
 function attrs

Replace direct calls to power supply function attributes with wrappers.
Wrappers provide safe access in case of unregistering the power
supply (e.g. by removing the driver). Replace:
 - get_property -> power_supply_get_property
