seeq: Move the SEEQ drivers

Move the drivers that use SEEQ chipset into drivers/net/ethernet/seeq
and make the necessary Kconfig and Makefile changes.

- * SEEQ nq8005 ethernet driver for Acorn/ANT Ether3 card
- *  for Acorn machines
- *
- * By Russell King, with some suggestions from borris@ant.co.uk
- *
- * Changelog:
- * 1.04	RMK	29/02/1996	Won't pass packets that are from our ethernet
- *				address up to the higher levels - they're
- *				silently ignored.  I/F can now be put into
- *				multicast mode.  Receiver routine optimised.
- * 1.05	RMK	30/02/1996	Now claims interrupt at open when part of
- *				the kernel rather than when a module.
- * 1.06	RMK	02/03/1996	Various code cleanups
- * 1.07	RMK	13/10/1996	Optimised interrupt routine and transmit
- *				routines.
- * 1.08	RMK	14/10/1996	Fixed problem with too many packets,
- *				prevented the kernel message about dropped
- *				packets appearing too many times a second.
- *				Now does not disable all IRQs, only the IRQ
- *				used by this card.
- * 1.09	RMK	10/11/1996	Only enables TX irq when buffer space is low,
- *				but we still service the TX queue if we get a
- *				RX interrupt.
- * 1.10	RMK	15/07/1997	Fixed autoprobing of NQ8004.
- * 1.11	RMK	16/11/1997	Fixed autoprobing of NQ8005A.
- * 1.12	RMK	31/12/1997	Removed reference to dev_tint for Linux 2.1.
- *      RMK	27/06/1998	Changed asm/delay.h to linux/delay.h.
- * 1.13	RMK	29/06/1998	Fixed problem with transmission of packets.
- *				Chip seems to have a bug in, whereby if the
- *				packet starts two bytes from the end of the
- *				buffer, it corrupts the receiver chain, and
- *				never updates the transmit status correctly.
- * 1.14	RMK	07/01/1998	Added initial code for ETHERB addressing.
- * 1.15	RMK	30/04/1999	More fixes to the transmit routine for buggy
- *				hardware.
- * 1.16	RMK	10/02/2000	Updated for 2.3.43
- * 1.17	RMK	13/05/2000	Updated for 2.3.99-pre8
