[PATCH] Make bind_interdomain_evtchn_to_irq() public

[jgross]

From: Juergen Gross <jgross@xxxxxxxx>

bind_interdomain_evtchn_to_irq() is currently a private function. It is used
only by bind_interdomain_evtchn_to_irqhandler() to register an irq-handler for
an event channel.

By making it public it is possible to use e.g. threaded interrupts with
interdomain event channels.
