nfp: preliminary support for NFP-3800

This series is the first step to add support to the NFP driver for the
new NFP-3800 device. In this first series the goal is to clean
up small issues found while adding support for the new device, prepare
an abstraction of the differences between the already supported devices
and the new Kestrel device and add the new PCI ID.

* Patch 1/11 and 2/11 starts by removing some dead code and incorrect
  assumptions found while working Kestrel support. Patch 3/11, 4/11 and
  5/11 cleans up and prepares for adding the new PCI ID for Kestrel.
* Patches 6/11, 7/11, 8/11, 9/11, 10/11 adds, plumb and populates a device
   information structure to abstract the differences between the existed
   supported devices (NFP-4000, NFP-5000 and NFP-6000) and the
   new device (NFP3800).
* Finally patch 11/11 adds the new PCI ID for Kestrel.

More work is needed to drive the new NFP-3800 device after this first
batch of patches the foundation is prepared for the follow up work.

Thanks to the work of all those who contributed to this work.
