amd: Move AMD (Lance) chipset drivers

Moves the drivers for the AMD chipsets into drivers/net/ethernet/amd/
and the necessary Kconfig and Makfile changes.

The au1000 (Alchemy) driver was also moved into the same directory
even though it is not a "Lance" driver.

-/* sun3lance.c: Ethernet driver for SUN3 Lance chip */
-/*
-
-  Sun3 Lance ethernet driver, by Sam Creasey (sammy@users.qual.net).
-  This driver is a part of the linux kernel, and is thus distributed
-  under the GNU General Public License.
-
-  The values used in LANCE_OBIO and LANCE_IRQ seem to be empirically
-  true for the correct IRQ and address of the lance registers.  They
-  have not been widely tested, however.  What we probably need is a
-  "proper" way to search for a device in the sun3's prom, but, alas,
-  linux has no such thing.
-
-  This driver is largely based on atarilance.c, by Roman Hodek.  Other
-  sources of inspiration were the NetBSD sun3 am7990 driver, and the
-  linux sparc lance driver (sunlance.c).
-
-  There are more assumptions made throughout this driver, it almost
-  certainly still needs work, but it does work at least for RARP/BOOTP and
-  mounting the root NFS filesystem.
