[SCSI] fc4: remove this and all associated drivers

This code has been slowly rotting for about eight years.  It's currently
impeding a few SCSI cleanups, and nobody seems to have hardware to test
it any more.  I talked to Dave Miller about it, and he agrees we can
delete it.  If anyone wants a software FC stack in future, they can
retrieve this driver from git.
