ice: add new VSI type for subfunctions
Add required plumbing for new VSI type dedicated to devlink subfunctions.
Make sure that the vsi is properly configured and destroyed. Also allow
loading XDP and AF_XDP sockets.
The first implementation of devlink subfunctions supports only one Tx/Rx
queue pair per given subfunction.
