xen: events: add xen_allocate_irq_{dynamic, gsi} and xen_free_irq
This is neater than open-coded calls to irq_alloc_desc_at and
irq_free_desc.
No intended behavioural change.
Note that we previously were not checking the return value of
irq_alloc_desc_at which would be failing for GSI<NR_IRQS_LEGACY
because the core architecture code has already allocated those for
us. Hence the additional check against NR_IRQS_LEGACY in
xen_allocate_irq_gsi.
