Create a binding for the Marvell MV88E6xxx DSA switches

This shows the path we could take with this, deprecating the
weird external bus thing.

I don't know what to do about the irq lines with a pointless
type flag that should be onecell:ed.

I need proper schema checking to add LED support to the
Marvell switch. Just how it is, it can't go on like this.

Andrew: if you have lots of ideas and want to do lots of
changes, feel free to just take over the patch set and do
what you like, this is an RFC after all.
