This patch adds basic support for the AMCC 460EX/460GT PPC's.
Enable high bandwidth access on 460EX/GT. This should/could probably be done on other PPC's too, like 440SPe. This is currently not used, but with this setup it is possible to use it later on in e.g. the Linux EMAC driver for performance gain.
