smsc: Move the SMC (SMSC) drivers

Moves the SMC (SMSC) drivers into drivers/net/ethernet/smsc/ and the
necessary Kconfig and Makefile changes.  Also did some cleanup
of NET_VENDOR_SMC Kconfig tag for the 8390 based drivers.

- * History:
- *   08/20/00  Arnaldo Melo       fix kfree(skb) in smc_hardware_send_packet
- *   12/15/00  Christian Jullien  fix "Warning: kfree_skb on hard IRQ"
- *   03/16/01  Daris A Nevil      modified smc9194.c for use with LAN91C111
- *   08/22/01  Scott Anderson     merge changes from smc9194 to smc91111
- *   08/21/01  Pramod B Bhardwaj  added support for RevB of LAN91C111
- *   12/20/01  Jeff Sutherland    initial port to Xscale PXA with DMA support
- *   04/07/03  Nicolas Pitre      unified SMC91x driver, killed irq races,
- *                                more bus abstraction, big cleanup, etc.
- *   29/09/03  Russell King       - add driver model support

- *                                - convert to use generic MII interface
- *                                - add link up/down notification
- *                                - don't try to handle full negotiation in
