power: supply: axp288_charger: Some minor cleanups
Remove info->health, info->present and info->online caching, as no code is reading the cached values. Remove if (changed) check before calling power_supply_changed(), we return early from axp288_charger_extcon_evt_worker if nothing has changed, so the check is not needed.
