[PATCH v2 3/3] doc: add Corigine information to nfp documentation

[Chaoyong He <chaoyong.he@corigine.com>]

From: Walter Heymans <walter.heymans@corigine.com>

Add Corigine information to the nfp documentation. The Network Flow
Processor (NFP) PMD is used by products from both Netronome and
Corigine.
