[PATCH] alpha: pci update

- Check for parent PCI bus instead of bridge device to break the
  look in common_swizzle(). Functionally it's the same, but it's
  cleaner for PC-style host bridges (nautiluses).
- Generic PCI setup changes finally went in (thanks to rmk), so that
  FIXME in common_init_pci() can go.
