- remove all of the PCI chips (8xx series) leaving only 720
- pull out stand alone initialisation code (driver becomes a chip only
  driver for NCR Q720 and Zalon)
- remove most vestiges of PCI support (chip driver should be bus neutral)
- tidy up typedefs
- remove simulated intfly (may need putting back for 770)
