Marius Strobl f27d082cdf - As suggested by OpenSolaris use up-burst-sizes for determining the
supported burst sizes.
- Add support for 64-bit burst sizes (required for SBus GEM).
- Failing to register as interrupt controller during attach shouldn't
  be fatal so just inform about this instead of panicing.
- Take advantage of KOBJMETHOD_END.
- Remove some redundant variables.
- Add missing const.
