[IA64] Fix PV driver domains - xen stubs

Stub out new hypercalls in the hypervisor.  The only odd one here is
map/unmap_pirq.  This seems to be for MSI support, which I don't believe
we currently support for driver domains, so this is actually similar to
the x86 code path.  The tools code doesn't allow us to return -ENOSYS
here :(
