power: supply: rk817_battery: Refactor code and update state-of-charge algorithm

Browse Source

This algorithm dynamically estimates a battery's total dischargeable
capacity by correlating real-time internal resistance (measured at
cutoff voltage) with instantaneous current under varying operational
conditions. To account for temperature-dependent resistance
characteristics, the method implements a worst-caseselection protocol:
comparing the measured internal resistance against the
room-temperaturereference value (25°C cutoff threshold) and adopting
the higher resistance value for capacity computation.
