raw/ioat: introduce vdev probe for DSA/idxd device

The Intel DSA devices can be exposed to userspace via kernel driver, so can
be used without having to bind them to vfio/uio. Therefore we add support
for using those kernel-configured devices as vdevs, taking as parameter the
individual HW work queue to be used by the vdev.
