Hot-pluggable multi-function devices should use PLATFORM_DEVID_AUTO to
avoid name collisions on the platform bus.
This driver currently uses the USB-device address as an id. This makes
name collisions unlikely, but it could still happen if two devices are
connected to separate buses and gets assigned the same address.
