I usually put device_type, compatible and reg at the top of the block,
to announce what the node actually is before giving all the details.

Also, apart from the stray space in the compatible, I'm guessing that
the 440EPx bridge is actually more-or-less like the PCI bridges on
other 4xx chips, so we should have a more general compatible string
too.

Is the 440EPx a vanilla PCI or a PCI-X bridge?  If the later that
should be reflected in the name and compatible as well.
