If we are going to do this it shouldn't be device specific (it should be
done in the framework since nothing is specific to the controller there)
but I'm not convinced that we should be doing it - this is all very
Linux specific.
The DT already has support for specifying flash layouts, can't those be
used (for example via chosen if they're not fixed for the board)? Or if
it's just picking the correct filesystem then UUIDs and labels are the
standard way to do things.
