xen: Remove unnecessary arch specific xen irq functions.
Right now xen's use of the x86 and ia64 handle_irq is just bizarre and very
fragile as it is very non-obvious the function exists and is is used by
code out in drivers/.... Luckily using handle_irq is completely unnecessary,
and we can just use the generic irq apis instead.
This still leaves drivers/xen/events.c as a problematic user of the generic
irq apis it has "static struct irq_info irq_info[NR_IRQS]" but that can be
fixed some other time.
