[SCSI] bfa: Add support for FC Arbitrated Loop topology.
- Add private loop topology support at 2G/4G/8G speeds with following limitations 1. No support for multiple initiators in the loop 2. No public loop support. If attached to a loop with an FL_Port, device continues to work as a private NL_Port in the loop 3. No auto topology detection. User has to manually set the configured topology to loop if attaching to loop. - When loop topology is configured, enabling FC port features QoS/Trunk/TRL are not allowed and vice versa.
