power: supply: max17042: consider task period (max77759)
Several (register) values reported by the fuel gauge depend on its
internal task period and it needs to be taken into account when
calculating results. All relevant example formulas in the data sheet
assume the default task period (of 5760) and final results need to be
adjusted based on the task period in effect.
Update the code as and where necessary.
