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.

-/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
-/*
-    Most of this driver, except for ultramca_probe is nearly
-    verbatim from smc-ultra.c by Donald Becker. The rest is
-    written and copyright 1996 by David Weis, weisd3458@uni.edu
-
-    This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
-
-    This driver uses the cards in the 8390-compatible, shared memory mode.
-    Most of the run-time complexity is handled by the generic code in
-    8390.c.
-
-    This driver enables the shared memory only when doing the actual data
-    transfers to avoid a bug in early version of the card that corrupted
-    data transferred by a AHA1542.
-
-    This driver does not support the programmed-I/O data transfer mode of
-    the EtherEZ.  That support (if available) is smc-ez.c.  Nor does it
-    use the non-8390-compatible "Altego" mode. (No support currently planned.)
-
-    Changelog:
-
-    Paul Gortmaker	 : multiple card support for module users.
-    David Weis		 : Micro Channel-ized it.
-    Tom Sightler	 : Added support for IBM PS/2 Ethernet Adapter/A
-    Christopher Turcksin : Changed MCA-probe so that multiple adapters are
-			   found correctly (Jul 16, 1997)
-    Chris Beauregard	 : Tried to merge the two changes above (Dec 15, 1997)
-    Tom Sightler	 : Fixed minor detection bug caused by above merge
-    Tom Sightler	 : Added support for three more Western Digital
-			   MCA-adapters
-    Tom Sightler	 : Added support for 2.2.x mca_find_unused_adapter
-    Hartmut Schmidt	 : - Modified parameter detection to handle each
-			     card differently depending on a switch-list
-			   - 'card_ver' removed from the adapter list
-			   - Some minor bug fixes
