for card change interrupts is different than the pci stuff that's coming soon. Set the management irq in different ways. If pci_parallel interrutp routing, then use the PCI way of getting interrupts. Move polling mode into pcic_isa since when we're routing via pci polling doesn't work because many bridges (systems hang solid). If we're routing interrupts via pci, they can be shared, so flag them as such. Note, this doesn't actually change anything since the pci attachment isn't quite ready to be committed.
