ixbmtr_cs: Move the IBM PCMCIA Token Ring driver

Move the IBM PCMCIA Token Ring driver into drivers/net/tokenring/ with
the other Token Ring drivers.  Made the necessary Kconfig and Makefile
changes as well.

-/*======================================================================
-
-    A PCMCIA token-ring driver for IBM-based cards
-
-    This driver supports the IBM PCMCIA Token-Ring Card.
-    Written by Steve Kipisz, kipisz@vnet.ibm.com or
-                             bungy@ibm.net
-
-    Written 1995,1996.
-
-    This code is based on pcnet_cs.c from David Hinds.
-    
-    V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
-
-    Linux V2.2.x presented significant changes to the underlying
-    ibmtr.c code.  Mainly the code became a lot more organized and
-    modular.
-
-    This caused the old PCMCIA Token Ring driver to give up and go 
-    home early. Instead of just patching the old code to make it 
-    work, the PCMCIA code has been streamlined, updated and possibly
-    improved.
-
-    This code now only contains code required for the Card Services.
-    All we do here is set the card up enough so that the real ibmtr.c
-    driver can find it and work with it properly.
-
-    i.e. We set up the io port, irq, mmio memory and shared ram
-    memory.  This enables ibmtr_probe in ibmtr.c to find the card and
-    configure it as though it was a normal ISA and/or PnP card.
-
-    CHANGES
-
-    v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
-    Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
-    
-    v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
-    Updated to version 2.2.7 to match the first version of the kernel
-    that the modification to ibmtr.c were incorporated into.
-    
-    v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
-    Address translation feature of PCMCIA controller is usable so
-    memory windows can be placed in High memory (meaning above
-    0xFFFFF.)
