The interrupt map wasn't being allocated properly, preventing IRQs from being allocated to children of the PCIe bus. Fix this by cloning the ofw_pcib_pci code, which handles all cases -- device tree and probed. In the future this may become a subclass of the ofw_pcib_pci driver, but as that's not an exported class, it's cloned for now. MFC after: 3 weeks
