[SCSI] libfc: Add support for FDMI
This patch adds support for Fabric Device Management Interface as per FC-GS-4 spec. in libfc. Any driver making use of libfc can enable fdmi state machine for a given lport. If lport has enabled FDMI support the lport state machine will transition into FDMI after completing the DNS states and before entering the SCR state. The FDMI state transition is such that if there is an error, it won't stop the lport state machine from transitioning and the it will behave as if there was no FDMI support. The FDMI HBA attributes are registed with the Management server via Register HBA (RHBA) command and the port attributes are reigstered using the Register Port(RPA) command.
