power: supply: ab8500: Standardize CV voltage
The voltage used in the constant voltage phase of the charging exist in struct power_supply_battery_info as constant_charge_voltage_max_uv. Switch the custom property normal_vol_lvl to this and consequentially change everything that relates to this value over to using microvolts rather than millivolts so we align internal representation of current with the power core. Prefix every variable we change with *_uv to indicate the unit everywhere but also to make sure we do not miss any outlier.
