usertools: support IOAT device binding

Browse Source 
In order to allow binding/unbinding of devices for use by the
ioat_rawdev, we need to update the devbind script to add a new class
of device, and add device ids for the specific HW instances.

For builds using ``meson`` and ``ninja``, the driver will be built when the
target platform is x86-based.
Device Setup
-------------
The Intel\ |reg| QuickData Technology HW devices will need to be bound to a
user-space IO driver for use. The script ``dpdk-devbind.py`` script
included with DPDK can be used to view the state of the devices and to bind
them to a suitable DPDK-supported kernel driver. When querying the status
of the devices, they will appear under the category of "Misc (rawdev)
devices", i.e. the command ``dpdk-devbind.py --status-dev misc`` can be
used to see the state of those devices alone.
