[SCSI] bfa: Revised Fabric Assigned Address(FAA) feature implementation.

Переглянути джерело 
Made changes to the Fabric Assigned Address(FAA) feature implementation.
Introduced the IOCFC state machine, which now handles the FAA logic,
IOC and BFA sub-modules enablement.
Removed un-wanted FAA enable/disable routines; FAA is enabled by default.
