[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.
