xen: setup pv irq ops vector earlier
Setting pv_irq_ops for Xen PV domains should be done as early as possible in order to support e.g. very early printk() usage. The same applies to xen_vcpu_info_reset(0), as it is needed for the pv irq ops. Move the call of xen_setup_machphys_mapping() after initializing the pv functions as it contains a WARN_ON(), too. Remove the no longer necessary conditional in xen_init_irq_ops() from PVH V1 times to make clear this is a PV only function.
