This is a good change in itself since it gets rid of some occasions
of the dreaded "cd-inverted" property. I think Martin Blumenstingl
already sent patches like these though (I might be confused).

But we should keep the old device trees working as well.
Can you test if Martins patch:

Also makes your boards work?
