ethoc: Add device tree configuration
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.
