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.

xen_piix_pci_write_config_client() is implemented in the xen sub tree and
uses PIIX constants internally, thus creating a direct dependency on
PIIX. Now that xen_set_pci_link_route() is stubbable, the logic of
xen_piix_pci_write_config_client() can be moved to PIIX which resolves
the dependency.

The only user of xen_set_pci_link_route() is
xen_piix_pci_write_config_client() which implements PIIX-specific logic in
the xen namespace. This makes xen-hvm depend on PIIX which could be
avoided if xen_piix_pci_write_config_client() was implemented in PIIX. In
order to do this, xen_set_pci_link_route() needs to be stubbable which
this patch addresses.

We should never build something that calls this without having it.
