power: supply: max17042_battery: use VF SOC register for capacity property
The capacity property uses the RepSOC register to report the current state
of charge. This register did not provide a reliable SOC value during my
testing with the max17047 variant on a Galaxy S3 (Trats2/GT-I9300). The
reported value did not change or even stayed 0 in some cases.
However, the VF SOC register provided an accurate SOC value at all times.
It uses the voltage fuel gauge to determine the SOC.
