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.

- *  tms380tr.c: A network driver library for Texas Instruments TMS380-based
- *              Token Ring Adapters.
- *
- *  Originally sktr.c: Written 1997 by Christoph Goos
- *
- *  A fine result of the Linux Systems Network Architecture Project.
- *  http://www.vanheusden.com/sna/ 
- *
- *  This software may be used and distributed according to the terms
- *  of the GNU General Public License, incorporated herein by reference.
- *
- *  The following modules are currently available for card support:
- *	- tmspci (Generic PCI card support)
- *	- abyss (Madge PCI support)
- *      - tmsisa (SysKonnect TR4/16 ISA)
- *
- *  Sources:
- *  	- The hardware related parts of this driver are take from
- *  	  the SysKonnect Token Ring driver for Windows NT.
- *  	- I used the IBM Token Ring driver 'ibmtr.c' as a base for this
- *  	  driver, as well as the 'skeleton.c' driver by Donald Becker.
- *  	- Also various other drivers in the linux source tree were taken
- *  	  as samples for some tasks.
- *      - TI TMS380 Second-Generation Token Ring User's Guide
- *  	- TI datasheets for respective chips
- *  	- David Hein at Texas Instruments 
- *  	- Various Madge employees
- *
- *  Maintainer(s):
- *    JS	Jay Schulist		jschlst@samba.org
- *    CG	Christoph Goos		cgoos@syskonnect.de
- *    AF	Adam Fritzler
- *    MLP       Mike Phillips           phillim@amtrak.com
- *    JF	Jochen Friedrich	jochen@scram.de
- *     
- *  Modification History:
- *	29-Aug-97	CG	Created
- *	04-Apr-98	CG	Fixed problems caused by tok_timer_check
- *	10-Apr-98	CG	Fixed lockups at cable disconnection
- *	27-May-98	JS	Formated to Linux Kernel Format
- *	31-May-98	JS	Hacked in PCI support
- *	16-Jun-98	JS	Modulized for multiple cards with one driver
- *	   Sep-99	AF	Renamed to tms380tr (supports more than SK's)
- *      23-Sep-99	AF      Added Compaq and Thomas-Conrad PCI support
- *				Fixed a bug causing double copies on PCI
- *				Fixed for new multicast stuff (2.2/2.3)
- *	25-Sep-99	AF	Uped TPL_NUM from 3 to 9
- *				Removed extraneous 'No free TPL'
- *	22-Dec-99	AF	Added Madge PCI Mk2 support and generalized
- *				parts of the initilization procedure.
- *	30-Dec-99	AF	Turned tms380tr into a library ala 8390.
- *				Madge support is provided in the abyss module
- *				Generic PCI support is in the tmspci module.
- *	30-Nov-00	JF	Updated PCI code to support IO MMU via
- *				pci_map_static(). Alpha uses this MMU for ISA
- *				as well.
- *      14-Jan-01	JF	Fix DMA on ifdown/ifup sequences. Some 
- *      			cleanup.
- *	13-Jan-02	JF	Add spinlock to fix race condition.
- *	09-Nov-02	JF	Fixed printks to not SPAM the console during
- *				normal operation.
- *	30-Dec-02	JF	Removed incorrect __init from 
- *				tms380tr_init_card.
- *	22-Jul-05	JF	Converted to dma-mapping.
- *      			
- *  To do:
- *    1. Multi/Broadcast packet handling (this may have fixed itself)
- *    2. Write a sktrisa module that includes the old ISA support (done)
- *    3. Allow modules to load their own microcode
- *    4. Speed up the BUD process -- freezing the kernel for 3+sec is
- *         quite unacceptable.
- *    5. Still a few remaining stalls when the cable is unplugged.
