max17042: Change capacity property to use reported SOC register

Quoted 17 lines

From: Dirk Brandewie

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.

Applied. But I don't get it: PROP_CAPACITY should report percents! And it looks that it reports something very different.

Also, if you look down the file, you'll see this:

case POWER_SUPPLY_PROP_CHARGE_FULL:
