while after the legacy device was added since this driver hangs from legacy and not nexus. - Make several methods non-static so they can be reused in a mptable host -> pci bridge driver that will be added at a later date. - Let legacy_pcib() use pcibios_pcib_route_interrupt() directly instead of wrapping it in a private function. Originally, I thought I was going to have the nexus_pcib() driver make a runtime APIC vs. 8259A check and call the appropriate routing method (MPTable vs. PIR) that way, but it ended up being cleaner to make nexus_pcib() just work with PIR and have a separate host -> pci bridge driver for the mptable/apic case.
