You haven't fixed the problem spotted by Rob which is that the example
is now out of sync, it's missing the required properties.

Also long run I think best is going to have a child node per downstream
port, so we create a matching linux struct device. This will make it
easier to deal with the other device-controller in the ast2600 which is
basically one of these without a vhub above it.
