Change bandit as found in many old world macs to use configuration type 1.
Alter range calculation to handle bandits dual non contiguous PCI memory spaces. Finally fix a bug whereby if the "AAPL,Interrupts" property is defined the variable intr isn't assigned a value and garbage may be written to the PCI interrupt register. tested by jolan, pedro, drahn and myself, and in snaps for a week. ok drahn, deraadt
