provides no ino-bitmap properties so forge them using the default set of controller interrupts and let schizo_setup_intr() take care of the children, hoping for non-fancy routing. - Add quirk handling for Sun Fire V890. When booting these machines from disk a Schizo comes up with PCI error residing which triggers as soon as we register schizo_pci_bus() even when clearing it from all involved registers (it's no longer indicated once we're in schizo_pci_bus() though). Thus make PCI bus errors non-fatal until we actually touch the bus. With this change schizo_pci_bus() typically triggers once during attach in this case. Obviously this approach isn't exactly race free but it's about the best we can do about this problem as we're not guaranteed that the interrupt will actually trigger on V890 either, as it certainly doesn't when for example netbooting them.
