The "multi-slot" concept I was talking about was one host controller
for several physical slots. Seems like at91 implements _and_ uses this
but nobody else. However, it seems that they allocate one mmc host per
slot, so the same model still works.

I think we need to be extra careful about the DT bindings then because
adding a property in a slot is requiring handling that in the at91
driver whereas adding a common property for the various mmc hosts can be
done in the core code.

From what I remember, it would be really good to put the DT parsing for

the slots in the core code but I only had a really quick look at that.
