In PVH dom0, when passthrough a device to domU, QEMU code xen_pt_realize->xc_physdev_map_pirq wants to use gsi, but in current codes the gsi number is got from file /sys/bus/pci/devices/<sbdf>/irq, that is wrong, because irq is not equal with gsi, they are in different spaces, so pirq mapping fails. To solve above problem, use new interface of Xen, xc_pcidev_get_gsi to get gsi and use xc_physdev_map_pirq_gsi to map pirq when dom0 is PVH.
