Marius Strobl d13ea234b3 - Add a workaround (change the interrupt map mask to compare the full
INO) for incorrect interrupt map entries on E250 machines. These
  incorrect entries caused the INO of the on-board HME to be also
  assigned to the second on-board NS16550 and to the on-board printer
  port controller. Further down the road caused hme(4) to fail to attach
  to the on-board HME in FreeBSD 5 and 6 as INTR_FAST and non-INTR_FAST
  handlers can't share the same IRQ there (it's unknown what whould
  happen in -CURRENT now that INTR_FAST and non-INTR_FAST handlers can
  share an IRQ but I'd expect funny problems with uart(4)).
- Make sure there are exactly 4 PCI ranges instead of just checking
  that the bridge has a 'ranges' property in the OFW device tree at all.
  Besides the fact that currently the 64bit memory range isn't used by
  this driver it we can't really work with less than 4 ranges and don't
  have memory for more than 4 bus handles for the ranges in the softc.
- Remove sc_range and sc_nrange from softc; for the bridges supported
  by this driver we no longer need to know the ranges besides the bus
  handles obtained from them once this driver is attached. That way we
  also can free the memory allocated for sc_range during attach again.
- Remove sc_dvmabase from the softc and pass it to psycho_iommu_init()
  via an additional argument as we no longer need to know the DVMA base
  in this driver once the IOMMU is initialized.
- Remove sc_dmatag from the softc, there isn't much sense in keeping
  the nexus dma tag around locally.
