Cédric Le Goater d3d1a40612 s390x/s390-virtio-ccw: Switch off zPCI enhancements on older machines
zPCI enhancement features (interpretation and forward assist) were
recently introduced to improve performance on PCI passthrough devices.
To maintain the same behaviour on older Z machines, deactivate the
features with the associated properties.
