power_supply: Add voltage_ocv property and use it for max17042 driver
This adds a new sysfs file called 'voltage_ocv' which gives the Open Circuit Voltage of the battery. This property can be used for platform shutdown policies and can be useful for initial capacity estimations. Note: This patch is generated against linux-next branch.
