This patch adds the ability to describe ethernet devices via a flattened device tree. As device tree remains an optional feature, these bits all need to be guarded by CONFIG_OF ifdefs. MAC address is settable via the device tree parameter "local-mac-address"; however, the selection of the phy id is limited to probing, for now.
