i40e: Adds FCoE related code to i40e core driver
Adds FCoE specific code to existing i40e core driver to:-
1. have separate FCoE VSI with additional FCoE queues pairs.
2. have FCoE related hash defines.
3. have additional FCoE related stats code.
4. export and then re-use existing functions required by FCoE build.
