Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

+ *  skisa.c: A network driver for SK-NET TMS380-based ISA token ring cards.
+ *
+ *  Based on tmspci written 1999 by Adam Fritzler
+ *  
+ *  Written 2000 by Jochen Friedrich
+ *  Dedicated to my girlfriend Steffi Bopp
+ *
+ *  This software may be used and distributed according to the terms
+ *  of the GNU General Public License, incorporated herein by reference.
+ *
+ *  This driver module supports the following cards:
+ *	- SysKonnect TR4/16(+) ISA	(SK-4190)
+ *
+ *  Maintainer(s):
+ *    AF        Adam Fritzler
+ *    JF	Jochen Friedrich	jochen@scram.de
+ *
+ *  Modification History:
+ *	14-Jan-01	JF	Created
+ *	28-Oct-02	JF	Fixed probe of card for static compilation.
+ *				Fixed module init to not make hotplug go wild.
+ *	09-Nov-02	JF	Fixed early bail out on out of memory
+ *				situations if multiple cards are found.
+ *				Cleaned up some unnecessary console SPAM.
+ *	09-Dec-02	JF	Fixed module reference counting.
+ *	02-Jan-03	JF	Renamed to skisa.c
