          - adds preliminary highspeed ISO support
          - tweaks the driver to support the Philips EHCI
          - does less in the IRQ handler
          - avoids accessing one immutable PCI register
      
    The ISO support should be enough to start writing
    drivers, not that I know of any ISO devices that are
    really available yet, but it's not fully cooked yet.
      
    As a functional milestone, this means Linux now
    handles all kinds of highspeed device I/O.  (But it
    doesn't yet handle split periodic transactions, to
    full or low speed devices through USB 2.0 hubs.)
        
    Thanks to Rory Bolt for the non-ISO bits here!
