kernel: allow device-tree configuration of at803x
This commit adds the ability to configure specific functions of the
at803x series ethernet-PHYs, which were previously configured
exclusively with the help of platform-data, via device-tree.
This is needed to fully support existing boards of the ar71xx platform.
