tokenring: delete all remaining driver support

This represents the mass deletion of the of the tokenring support.

It gets rid of:
  - the net/tr.c which the drivers depended on
  - the drivers/net component
  - the Kbuild infrastructure around it
  - any tokenring related CONFIG_ settings in any defconfigs
  - the tokenring headers in the include/linux dir
  - the firmware associated with the tokenring drivers.
  - any associated token ring documentation.

-/* ibmtr.c:  A shared-memory IBM Token Ring 16/4 driver for linux
- *
- *	Written 1993 by Mark Swanson and Peter De Schrijver.
- *	This software may be used and distributed according to the terms
- *	of the GNU General Public License, incorporated herein by reference.
- *
- *	This device driver should work with Any IBM Token Ring Card that does
- *	not use DMA.
- *
- *	I used Donald Becker's (becker@scyld.com) device driver work
- *	as a base for most of my initial work.
- *
- *	Changes by Peter De Schrijver
- *		(Peter.Deschrijver@linux.cc.kuleuven.ac.be) :
- *
- *	+ changed name to ibmtr.c in anticipation of other tr boards.
- *	+ changed reset code and adapter open code.
- *	+ added SAP open code.
- *	+ a first attempt to write interrupt, transmit and receive routines.
- *
- *	Changes by David W. Morris (dwm@shell.portal.com) :
- *	941003 dwm: - Restructure tok_probe for multiple adapters, devices.
- *	+ Add comments, misc reorg for clarity.
- *	+ Flatten interrupt handler levels.
- *
- *	Changes by Farzad Farid (farzy@zen.via.ecp.fr)
- *	and Pascal Andre (andre@chimay.via.ecp.fr) (March 9 1995) :
- *	+ multi ring support clean up.
- *	+ RFC1042 compliance enhanced.
- *
- *	Changes by Pascal Andre (andre@chimay.via.ecp.fr) (September 7 1995) :
- *	+ bug correction in tr_tx
- *	+ removed redundant information display
- *	+ some code reworking
- *
- *	Changes by Michel Lespinasse (walken@via.ecp.fr),
- *	Yann Doussot (doussot@via.ecp.fr) and Pascal Andre (andre@via.ecp.fr)
- *	(February 18, 1996) :
- *	+ modified shared memory and mmio access port the driver to
- *	  alpha platform (structure access -> readb/writeb)
- *
- *	Changes by Steve Kipisz (bungy@ibm.net or kipisz@vnet.ibm.com)
- *	(January 18 1996):
- *	+ swapped WWOR and WWCR in ibmtr.h
- *	+ moved some init code from tok_probe into trdev_init.  The
- *	  PCMCIA code can call trdev_init to complete initializing
- *	  the driver.
- *	+ added -DPCMCIA to support PCMCIA
- *	+ detecting PCMCIA Card Removal in interrupt handler.  If
- *	  ISRP is FF, then a PCMCIA card has been removed
- *        10/2000 Burt needed a new method to avoid crashing the OS
- *
- *	Changes by Paul Norton (pnorton@cts.com) :
- *	+ restructured the READ.LOG logic to prevent the transmit SRB
- *	  from being rudely overwritten before the transmit cycle is
- *	  complete. (August 15 1996)
- *	+ completed multiple adapter support. (November 20 1996)
- *	+ implemented csum_partial_copy in tr_rx and increased receive 
- *        buffer size and count. Minor fixes. (March 15, 1997)
- *
- *	Changes by Christopher Turcksin <wabbit@rtfc.demon.co.uk>
- *	+ Now compiles ok as a module again.
- *
- *	Changes by Paul Norton (pnorton@ieee.org) :
- *      + moved the header manipulation code in tr_tx and tr_rx to
- *        net/802/tr.c. (July 12 1997)
- *      + add retry and timeout on open if cable disconnected. (May 5 1998)
- *      + lifted 2000 byte mtu limit. now depends on shared-RAM size.
- *        May 25 1998)
- *      + can't allocate 2k recv buff at 8k shared-RAM. (20 October 1998)
- *
- *      Changes by Joel Sloan (jjs@c-me.com) :
- *      + disable verbose debug messages by default - to enable verbose
- *	  debugging, edit the IBMTR_DEBUG_MESSAGES define below 
- *	
- *	Changes by Mike Phillips <phillim@amtrak.com> :
- *	+ Added extra #ifdef's to work with new PCMCIA Token Ring Code.
- *	  The PCMCIA code now just sets up the card so it can be recognized
- *        by ibmtr_probe. Also checks allocated memory vs. on-board memory
- *	  for correct figure to use.
- *
- *	Changes by Tim Hockin (thockin@isunix.it.ilstu.edu) :
- *	+ added spinlocks for SMP sanity (10 March 1999)
- *
- *      Changes by Jochen Friedrich to enable RFC1469 Option 2 multicasting
- *      i.e. using functional address C0 00 00 04 00 00 to transmit and 
- *      receive multicast packets.
- *
- *      Changes by Mike Sullivan (based on original sram patch by Dave Grothe
- *      to support windowing into on adapter shared ram.
- *      i.e. Use LANAID to setup a PnP configuration with 16K RAM. Paging
- *      will shift this 16K window over the entire available shared RAM.
- *
- *      Changes by Peter De Schrijver (p2@mind.be) :
- *      + fixed a problem with PCMCIA card removal
- *
- *      Change by Mike Sullivan et al.:
- *      + added turbo card support. No need to use lanaid to configure
- *      the adapter into isa compatibility mode.
- *
- *      Changes by Burt Silverman to allow the computer to behave nicely when
- *	a cable is pulled or not in place, or a PCMCIA card is removed hot.
