If it helps, fwupd already uses mtd for other devices too, although at
the moment we're using it only for system firmware -- e.g. intel-spi
style. The MTD subsystem doesn't give fwupd much info about the
{removable} device itself, and that can pose a problem unless you
start using heuristics about the parent device to match firmware to
the mtd device.
