[PATCH] net: add driver for the NIC on Cell Blades

This patch adds a driver for a new 1000 Mbit ethernet NIC.  It is
integrated on the south bridge that is used for our Cell Blades.

The code gets the MAC address from the Open Firmware device tree, so it
won't compile on platforms other than ppc64.

This is the first public release, so I don't expect the first version to
get merged, but I'd aim for integration within the 2.6.13 time frame.
