In order to limit the deployment to a specific device type,
use one of kustomizations under deployments/operator/device.

For example, to limit the deployment to FPGA, use:

```bash
$ kubectl apply -k deployments/operator/device/fpga
```

Operator also supports deployments with multiple selected device types.
In this case, create a new kustomization with the necessary resources
that passes the desired device types to the operator using `--device`
command line argument multiple times.

the CRDs for other device types are still created, but no controllers
for them are registered.
