[Qemu-ppc] [PATCH] 40p: fix PCI interrupt routing

[Mark Cave-Ayland]

According to the PReP specification section 6.1.6 "System Interrupt
Assignments", all PCI interrupts are routed via IRQ 15.

With this patch applied it is now possible to boot the sandalfoot
zImage all the way through to a working userspace when using
OpenBIOS.
