QEMU 2.12 introduced a new vfio-pci device option 'display=on/off/auto'.
Initially, libvirt is only going to support values on/off only, as we
don't want to predict what the intended usage of the mediated device
will be and most importantly, what kind of vfio display implementation
to use - dmabuf vs vfio region mapping as there's no convenient way for
us to find out what implementation the device's underlying driver
supports.
