power: supply: max17040: remove non-working POWER_SUPPLY_PROP_STATUS
The driver was reporting POWER_SUPPLY_PROP_STATUS via platform data functions. Without platform data, the max17040_get_status() functions returns early with POWER_SUPPLY_STATUS_UNKNOWN. Since there are no platforms using the driver with platform data (no board files with the driver), the status property was always unknown.
