power: supply: max17042_battery: Separate MAX17055 initialization
MAX17055 uses ModelCfg.Refresh instead of the characterization-data
flow used by the other supported gauges. Move its existing initialization
steps into a dedicated helper without changing behavior. This isolates the
chip-specific path for subsequent EZ Config changes.
