Changes: Added a pci-EISA bridge device and associated glue to the prep port. Adapted from i386. Change pci_intr_fixup_*() to pass the pin argument on all platforms. Make PCI_NETBSD_CONFIGURE leave the MPIC alone. We map it separately. 7024 kernel was also succ. tested on an IBM 7043, so no regression there.
