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