[v2,5/6] usertools/dpdk-devbind.py: add support for ntb

  In order to allow binding/unbinding of devices for use by the
ntb_rawdev, we need to update the devbind script to add a new class
of device, and add device ids for the specific HW instances. And
only support skx platform right now.

Looking at this patch, and my own rawdev set for adding the ioat driver, I
wonder if it's really a good idea to add new categories for each rawdev
device type. Given we don't know how many device types there will be
overall, I wonder if it's better to just add a "misc" or "other" device
type section, where we put all raw devices.

Well. Seems a good idea. I don't think there will be too many communication devices or dma devices anyway.
So use misc_devices? I can align with you.
