- 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.
