Out of this patch's scope, but I need to ask anyway: do devices on a
spapr-vio bus have a unique address? If yes, what is it?

Is it okay to share interrupts? I'm asking because spapr_allocate_irq()
will happily assign IRQs already used via property. From PATCH 1/1:
static inline int spapr_allocate_irq(sPAPREnvironment *spapr)
{
return spapr->next_irq++;
}
