Why not just replace the calls to fat_register_device() with calls to
get_device_and_partition() (perhaps some wrapper is needed to make the
APIs match). That way, someone (U-Boot config file author I suppose) can
always specify exactly what they want, without needing any
non-deterministic fallbacks.
