I was expecting this one change to fix the issue since the if() block
should be compiled away removing references to davinci_mdio_probe_dt().
The code does get compiled out and there are no references to
davinci_mdio_probe_dt() in the final object when !CONFIG_OF.
But the compile error remains if the #ifdefs you removed above are
installed back. Not sure why.
Thanks,
Sekhar
