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.

the ifdef seems superfluous and again this should be part of the
at803x_priv struct. however looking at the current code it seems that
the patchery is inconsistent and the driver is pretty messy. we should
consider cleaning this up and consolidating the driver patches and move
them to generic/
