marius cdec2d0d7a - Ensure we find no unexpected partner.
- Failing to register as interrupt controller during attach shouldn't
  be fatal so just inform about this instead of panicing.
- Disable rerun of the streaming cache as workaround for a silicon bug
  of certain Psycho versions.
- Remove the comment regarding lack of newbus'ified bus_dma(9) as being
  able to associate a DMA tag with a device would allow to implement
  CDMA flushing/syncing in bus_dmamap_sync(9) but that would totally
  kill performance. Given that for devices not behind a PCI-PCI bridge
  the host-to-PCI bridges also only do CDMA flushing/syncing based on
  interrupts there's no additional disadvantage for polling(4) callbacks
  in the case schizo(4) has to do the CDMA flushing/syncing but rather a
  general problem.
- Don't panic if the power failure, power management or over-temperature
  interrupts doesn't exist as these aren't mandatory and not available
  with all controllers (not even Psychos). [1]
- Take advantage of KOBJMETHOD_END.
- Remove some redundant variables.
- Add missing const.
