Hmm, ethernet in SPL. Haven't thought of that :-)

While it could be easy to move the DTS part of  PHY mode configuration into
the driver, moving the reset portion of that code into the driver would be ugly
unless using proper reset management?

Would it work for you to change this into:

#if defined CONFIG_ETH_DESIGNWARE && !CONFIG_IS_ENABLED(OF_PLATDATA)

We could still fix the reset code when actually using OF_PLATDATA with
ethernet...
