Something that has a #address-cells larger than 2, or more generally,
an address field that contains more than a single number, must have
a specific translation backend, like we have for PCI.
This is a bit annoying but originates from the original OFW stuff on
which this stuff is based where the bus node would provide the methods
for translation.
Cheers,
Ben.
