[PATCH V3 5/7] power: supply: rk817-charger: Expose boot voltage and OCV values

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Expose PWRON_VOL as POWER_SUPPLY_PROP_VOLTAGE_BOOT and the current
rested pair as POWER_SUPPLY_PROP_VOLTAGE_OCV. The OCV value will
return -ENODATA while the battery is not resting.
