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.
