Get a very primitive relation of IRQ affinity working.  For the
minute, we just pick one vcpu out of the allowed set and allows route
the irq to that one; that's enough for the userspace irq balancer, but
not enough for the kernel-space one.

Whether it's actually worth implementing the full variant is open to
debate.

This also makes IRQ routing across vcpu hotplug events slightly
easier.
