pseries: Refactor spapr irq allocation
Paulo Bonzini changed the original spapr code, which manually assigned irq numbers for each virtual device, to allocate them automatically from the device initialization. That allowed spapr virtual devices to be constructed with -device, which is a good start. However, the way that patch worked doesn't extend nicely for the future when we want to support devices other than sPAPR VIO devices (e.g. virtio and PCI). This patch rearranges the irq allocation to be global across the sPAPR environment, so it can be used by other bus types as well.
