[Qemu-ppc] [PULL 22/29] spapr-pci: enable irqfd for INTx |

From: Alexey Kardashevskiy <address@hidden>
This enables IRQFD for LSI (level triggered INTx interrupts) by adding
a spapr_route_intx_pin_to_irq() callback to the sPAPR PCI host bus. This
callback is called to know the global interrupt number to link resampling fd
with IRQFD's fd in KVM.
