fix "translate Xen-provided PIRQs" patch.

This patch fixes the ia64 breakage caused by 660:7886619f623e.
The change set is very x86 specific. So the functions, evtchn_map_pirq(),
evtchn_get_xen_pirq() should be arch specific.

However the pulling out those function out from evntchan would be
very ugly because they use static functions in the file.
Eventually the issue in the upstream linux will be addressed by pv_ops, 
and it doesn't matter much on 2.6.18-xen for ia64. So I keep this patch
as small as possible for now.
