The firmware of the real PegasosII board routes all PIRQx to IRQ9, so do
the same in QEMU. The PCI_INTERRUPT_LINE registers of the respective
internal PCI functions are already initialized with IRQ9 which are
currently used for routing.
Note that the PCI interrupt router isn't implemented yet in the VIA
south bridges. This change has therefore no effect until this happens.
