Enable OVS-DPDK support on arm64

[Christian Ehrhardt ]

DPDK works on arm64 since yakkety, and upstream worked on further stabilizing it.
For the Artful cycle we should try to enable OVS-DPDK on arm64.

This needs the new DPDK 17.05 to be completed and will therefore be part of this work.

Patch prepared and generally working, but since OVS 2.7 is not yet DPDK 17.05 compatible this change is blocked by the other.

[Christian Ehrhardt  (paelzer)]

Since we want to support thunderx/cavium but for the Artful cycle look at OVS 2.7 and thereby DPDK 16.11 this will need some backports to fix up the handling of these devices.
The intention is to later on apply all of the 16.11.2 stable release - but for now adding a DPDK task to work on backporting the important nicvf related fixed.
