remove the broken SKMC driver

The SKMC driver has:
- already been marked as BROKEN in 2.6.0 three years ago and
- is still marked as BROKEN.

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

-
-  Missing things:
-
-  -> set debug level via ioctl instead of compile-time switches
-  -> I didn't follow the development of the 2.1.x kernels, so my
-     assumptions about which things changed with which kernel version
-     are probably nonsense
-
-History:
-  May 16th, 1999
-  	startup
-  May 22st, 1999
-	added private structure, methods
-        begun building data structures in RAM
-  May 23nd, 1999
-	can receive frames, send frames
-  May 24th, 1999
-        modularized initialization of LANCE
-        loadable as module
-	still Tx problem :-(
-  May 26th, 1999
-  	MC2 works
-  	support for multiple devices
-  	display media type for MC2+
-  May 28th, 1999
-	fixed problem in GetLANCE leaving interrupts turned off
-        increase TX queue to 4 packets to improve send performance
-  May 29th, 1999
-	a few corrections in statistics, caught rcvr overruns
-        reinitialization of LANCE/board in critical situations
-        MCA info implemented
-	implemented LANCE multicast filter
-  Jun 6th, 1999
-	additions for Linux 2.2
-  Dec 25th, 1999
-  	unfortunately there seem to be newer MC2+ boards that react
-  	on IRQ 3/5/9/10 instead of 3/5/10/11, so we have to autoprobe
-  	in questionable cases...
-  Dec 28th, 1999
-	integrated patches from David Weinehall & Bill Wendling for 2.3
-	kernels (isa_...functions).  Things are defined in a way that
-        it still works with 2.0.x 8-)
-  Dec 30th, 1999
-	added handling of the remaining interrupt conditions.  That
-        should cure the spurious hangs.
-  Jan 30th, 2000
-	newer kernels automatically probe more than one board, so the
-	'startslot' as a variable is also needed here
-  June 1st, 2000
-	added changes for recent 2.3 kernels
