xen: events: refactor GSI pirq bindings functions
Following the example set by xen_allocate_pirq_msi and xen_bind_pirq_msi_to_irq: xen_allocate_pirq becomes xen_allocate_pirq_gsi and now only allocates a pirq number and does not bind it. xen_map_pirq_gsi becomes xen_bind_pirq_gsi_to_irq and binds an existing pirq.
