The device tree simply describes the hardware; if the hardware
connects both INTXs to the same IPIC interrupt pin, then it is
correct.  You'll have to ask a hardware designer whether it is
okay to just tie the two lines together; I believe it is, for
PCI, but you better ask someone who really knows :-)
