[SCSI] bfa: Changes to support FDMI Driver Parameter

 Added a FCS function to be called during driver init, to set the FDMI
 Driver parameter.

fdmi.c: Created a disabled state when fdmi is disabled.

bfad.c:
  * Added fdmi_enable driver parameter.
  * Added support to call bfa_fcs_set_fdmi_param() to initialize fcs
    fdmi setting.
