Remove long-unmaintained ftape driver subsystem.

It's bitrotten, long unmaintained, long hidden under BROKEN_ON_SMP,
etc.  As scheduled in feature-removal-schedule.txt, and ack'd several

drivers/char/ftape/README.PCI

-Some notes for ftape users with PCI motherboards:
-=================================================
-
-The problem:
-------------
-
-There have been some problem reports from people using PCI-bus based
-systems getting overrun errors.
-I wasn't able to reproduce these until I ran ftape on a Intel Plato
-(Premiere PCI II) motherboard with bios version 1.00.08AX1.
-It turned out that if GAT (Guaranteed Access Timing) is enabled (?)
-ftape gets a lot of overrun errors.
-The problem disappears when disabling GAT in the bios.
-Note that Intel removed this setting (permanently disabled) from the
-1.00.10AX1 bios !
-
-It looks like that if GAT is enabled there are often large periods
-(greater than 120 us !??) on the ISA bus that the DMA controller cannot
-service the floppy disk controller.
-I cannot imagine this being acceptable in a decent PCI implementation.
-Maybe this is a `feature' of the chipset. I can only speculate why
-Intel choose to remove the option from the latest Bios...
-
-The lesson of this all is that there may be other motherboard
-implementations having the same of similar problems.
-If you experience a lot of overrun errors during a backup to tape,
-see if there is some setting in the Bios that may influence the
-bus timing.
-
-I judge this a hardware problem and not a limitation of ftape ;-)
-My DOS backup software seems to be suffering from the same problems
-and even refuses to run at 1 Mbps !
-Ftape will reduce the data-rate from 1 Mbps to 500 Kbps if the number
-of overrun errors on a track exceeds a threshold.
-
-
-Possible solutions:
--------------------
-
-Some of the problems were solved by upgrading the (flash) bios.
-Other suggest that it has to do with the FDC being on the PCI
-bus, but that is not the case with the Intel Premiere II boards.
-[If upgrading the bios doesn't solve the problem you could try
-a floppy disk controller on the isa-bus].
-
-Here is a list of systems and recommended BIOS settings:
-
-
-        Intel Premiere PCI (Revenge):
-
-Bios version 1.00.09.AF2 is reported to work.
-
-
-
-        Intel Premiere PCI II (Plato):
-
-Bios version 1.00.10.AX1 and version 11 beta are ok.
-If using version 1.00.08.AX1, GAT must be disabled !
-
-
-
-        ASUS PCI/I-SP3G:
-
-Preferred settings:     ISA-GAT-mode : disabled
-                        DMA-linebuffer-mode : standard
-                        ISA-masterbuffer-mode : standard
-
-
-        DELL Dimension XPS P90
-
-Bios version A2 is reported to be broken, while bios version A5 works.
-You can get a flash bios upgrade from http://www.dell.com
-
-
-To see if you're having the GAT problem, try making a backup
-under DOS. If it's very slow and often repositions you're
-probably having this problem.

-   The entire guts of this program was written by dosemu, modified to
-   record reads and writes to the ports in the 0x180-0x188 address space,
-   while running the CMS program TAPE.EXE V2.0.5 supplied with the drive.
-
-   Modified to use an array of addresses and generally cleaned up (made
-   much shorter) 4 June 94, dosemu isn't that good at writing short code it
-   would seem :-). Made independent of 0x180, but I doubt it will work
-   at any other address.
-
-   Modified for distribution with ftape source. 21 June 94, SJL.
-
-   Modifications on 20 October 95, by Daniel Cohen (catman@wpi.edu):
-   Modified to support different DMA, IRQ, and IO Ports.  Borland's
-   Turbo Debugger in virtual 8086 mode (TD386.EXE with hardware breakpoints
-   provided by the TDH386.SYS Device Driver) was used on the CMS program
-   TAPE V4.0.5.  I set breakpoints on I/O to ports 0x180-0x187.  Note that
-   CMS's program will not successfully configure the tape drive if you set
-   breakpoints on IO Reads, but you can set them on IO Writes without problems.
-   Known problems:
-   - You can not use DMA Channels 5 or 7.
-
-   Modification on 29 January 96, by Daniel Cohen (catman@wpi.edu):
-   Modified to only accept IRQs 3 - 7, or 9.  Since we can only send a 3 bit
-   number representing the IRQ to the card, special handling is required when
-   IRQ 9 is selected.  IRQ 2 and 9 are the same, and we should request IRQ 9
-   from the kernel while telling the card to use IRQ 2.  Thanks to Greg
-   Crider (gcrider@iclnet.org) for finding and locating this bug, as well as
-   testing the patch.
-
-   Modification on 11 December 96, by Claus Heine (claus@momo.math.rwth-aachen.de):
-   Modified a little to use variahle ft_fdc_base, ft_fdc_irq, ft_fdc_dma 
-   instead of preprocessor symbols. Thus we can compile this into the module
-   or kernel and let the user specify the options as command line arguments.
