David Woodhouse 886e0a5f31 hw/isa/ich9: Add comment on imperfect emulation of PIC vs. I/O APIC routing
As noted in the comment, the PCI INTx lines are supposed to be routed
to *both* the PIC and the I/O APIC. It's just that we don't cope with
the concept of an IRQ being asserted to two *different* pins on the
two irqchips.

So we have this hack of routing to I/O APIC only if the PIRQ routing to
the PIC is disabled. Which seems to work well enough, even when I try
hard to break it with kexec. But should be explicitly documented and
understood.
