Add basic support for the internal ethernet switch on bcm6368. It behaves as a dumb switch for now, but allows basic connectivity. Also drop the ethernet patch for bcm6345 for now, it needs rework. SVN-Revision: 31129

Reorder patches for a clearer distinction between the purposes of the different patches. SVN-Revision: 31127
