Make the HCD initialization sequence more sane ... notably, setting up
root hubs before HCDs are asked to do their one-time init.  Among other
things, that lets the HCDs do custom root hub init along with all the
other one-time initialization done in the (now misnamed) reset() method.

This also copies the controller wakeup flags into the root hub; it's
done a bit later than would be ideal, but that'll be necessary until
the PCI code initializes them correctly.  (The PCI patch breaks on PPC
due to how it sequences PCI initialization.)
