max17042: Change capacity property to use reported SOC register
The SOC register (0dh) reports the state of charge before empty compensation adjustments are applied. The max value reported by this register will decrease as the battery ages. Use the RepSOC register (06h) to report the capacity of the battery. RepSOC contains a filtered version of the battery capacity after empty compensation adjustments have been applied.
