  Log:
  - Register the PCI bus error interrupt handler according to which half of
    the bridge (PCI bus A or B) we are attaching to rather than registering
    both handlers at once when attaching to the first half we encounter.
    This is a bit cleaner as it corresponds to which PCI bus error interrupt
    actually is assigned to the respective half by the OFW and allows to
    collapse both PCI bus error interrupt handlers into one function easily.
  - Use the actual RID of the respective interrupt resource as index into
    sc_irq_res and also use it when allocating the resource. For now this
    is a bit cleaner and will be mandatory later on.
  - According to OpenSolaris the spare hardware interrupt is used as the
    over-temperature interrupt in systems with Psycho bridges. Unlike as
    with the SBus-based workstations I didn't manage to trigger it when
    covering the fan outlets of an U60 but better be safe than sorry and
    register a handler anyway.
