Remove the vfio.sh utility file.

The suggested configuration method is by using the openshift sr-iov operator.
Also, change the doc mentioning the operator.

+The best way to configure your SR-IOV devices is by using the [OpenShift SR-IOV operator](https://github.com/openshift/sriov-network-operator).

+It will setup the devices according to the configuration provided and it will deploy the components needed to make SR-IOV work in your cluster (in particular, the [SR-IOV CNI plugin](https://github.com/intel/sriov-cni) and the [SR-IOV device plugin](https://github.com/intel/sriov-network-device-plugin)).
 
-Finally, create a new SR-IOV network CRD that will use SR-IOV device plugin to allocate devices.
+The OpenShift SR-IOV quickstart guide can be found [here](https://github.com/openshift/sriov-network-operator/blob/master/doc/quickstart.md). They provide instructions to run the operator both on Kubernetes and OpenShift.
