Make sure to always honour multi-function devices registered with PLATFORM_DEVID_NONE (-1) or PLATFORM_DEVID_AUTO (-2) as id base. In this case it does not make sense to append the cell id to the mfd-id base and potentially change the requested behaviour. Specifically this will allow multi-function devices to be registered with PLATFORM_DEVID_AUTO while still having non-zero cell ids.
