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.

V2: rather than adding a DMA section, add to "misc (rawdev)" section where
other device types, e.g. ntb can also do.
NOTE: this set largely overlaps with the equivalent changes made by the
patchset adding NTB support [1]. Since it's unclear which set will be added
first, this set is based off the latest head.

+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.
