8390: Move the 8390 related drivers

Moves the drivers for the National Semi-conductor 8390 chipset into
drivers/net/ethernet/8390/ and the necessary Kconfig and Makefile
changes.

-	lne390.c
-
-	Linux driver for Mylex LNE390 EISA Network Adapter
-
-	Copyright (C) 1996-1998, Paul Gortmaker.
-
-	This software may be used and distributed according to the terms
-	of the GNU General Public License, incorporated herein by reference.
-
-	Information and Code Sources:
-
-	1) Based upon framework of es3210 driver.
-	2) The existing myriad of other Linux 8390 drivers by Donald Becker.
-	3) Russ Nelson's asm packet driver provided additional info.
-	4) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
-
-	The LNE390 is an EISA shared memory NS8390 implementation. Note
-	that all memory copies to/from the board must be 32bit transfers.
-	There are two versions of the card: the lne390a and the lne390b.
-	Going by the EISA cfg files, the "a" has jumpers to select between
-	BNC/AUI, but the "b" also has RJ-45 and selection is via the SCU.
-	The shared memory address selection is also slightly different.
-	Note that shared memory address > 1MB are supported with this driver.
-
-	You can try <http://www.mylex.com> if you want more info, as I've
-	never even seen one of these cards.  :)
-
-	Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/09/01
-	- get rid of check_region
-	- no need to check if dev == NULL in lne390_probe1
