[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.

- * There are two kinds of Fibre Channel adapters used in Linux. Either
- * the adapter is "smart" and does all FC bookkeeping by itself and
- * just presents a standard SCSI interface to the operating system
- * (that's e.g. the case with Qlogic FC cards), or leaves most of the FC
- * bookkeeping to the OS (e.g. soc, socal). Drivers for the former adapters
- * will look like normal SCSI drivers (with the exception of max_id will be
- * usually 127), the latter on the other side allows SCSI, IP over FC and other
- * protocols. This driver tree is for the latter adapters.
- *
- * This file should support both Point-to-Point and Arbitrated Loop topologies.
