[PATCH v2 1/6] include/hw/xen/xen: Rename xen_piix3_set_irq() to xen_intx_set_irq()



xen_piix3_set_irq() isn't PIIX specific: PIIX is a single PCI device
while xen_piix3_set_irq() maps multiple PCI devices to their respective
IRQs, which is board-specific. Rename xen_piix3_set_irq() to communicate
this.

Also rename XEN_PIIX_NUM_PIRQS to XEN_IOAPIC_NUM_PIRQS since the Xen's
IOAPIC rather than PIIX has this many interrupt routes.
