  Accept special node naming variants for Marvell switches with
special node names as ABI.

This is maybe not the prettiest but it avoids special-casing
the Marvell MV88E6xxx bindings by copying a lot of generic
binding code down into that one binding just to special-case
these unfixable nodes.

As you say, not pretty. But it does the job.
