interrupt to be used for a device. This is intended solely for internal use of PCI bus implementations, and exists so that PCI bus drivers implementing special interrupt assignment methods which require additional work at the bus level to work right can be easily derived from the generic driver (or any other one) without resorting to hacks. It will be used in the sparc64 ofw_pcibus driver, which will be committed shortly. Make use of this method in the generic implementation, and add it to the method table of bus drivers derived from the PCI one. Reviewed by: imp, -hackers
