Subject: [PATCH RESEND v2 7/8] power: bq2415x_charger: 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
