Allow all unused GSI to be configured via IO-APIC by new pv_ops dom0
Currently Xen disallows setting up any GSI < 16. This makes it
impossible by the kernel to use any PCI devices without ACPI override
but a mapping to this interrupts via IO-APIC.
The patch allows all unused interrupts to be setup via IO-APIC.
