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.
