  SVN rev 183053 on 2008-09-15 22:26:32Z by jhb
  
  Rework the handling of interrupt handlers for children of ppc and ppbus:
  - Retire IVARs for passing IRQs around.  Instead, ppbus and ppc now allow
    child devices to access the interrupt by via a rid 0 IRQ resource
    using bus_alloc_resource_any().
  - ppc creates its own interrupt event to manage the interrupt handlers of
    child devices.  ppc does not allow child devices to use filters.  It
    could allow this if needed, but none of the current drivers use them
    and it adds a good bit of complication.  It uses
    intr_event_execute_handlers() to fire the child device interrupt handlers
    from its threaded interrupt handler.
  - Remove the ppbus_dummy_intr() hack.  Now the ppc device always has an
    interrupt handler registered and we no longer bounce all the way up to
    nexus to manage adding/removing ppbus child interrupt handlers.  Instead,
    the child handlers are added and removed to the private interrupt event
    in the ppc device.
