power: supply: sc27xx: Fix the incorrect formula when converting capacity to coulomb counter

Browse Source 
We should multiply the calibrated current data (cur_1000ma_adc) when
converting current capacity (mAh) to coulomb counter, which can get
an accurate coulomb counter from the fuel gauge controller.
