[Xen-devel] [PATCH] xen/arm: route irqs to cpu0

gic_route_irq_to_guest routes all IRQs to
cpumask_of(smp_processor_id()), but actually it always called on cpu0.
To avoid confusion and possible issues in case someone modified the code
and reassigned a particular irq to a cpu other than cpu0, hardcode
