I would prefer to avoid that. I would suggest you do what i did for
the none DT case. First probe using C22 for all devices known in DT.
Then call mdiobus_prevent_c45_scan() which will determine if any of
the found devices are FUBAR and will break C45. Then do a second probe
using C45 and/or C45 over C22 for those devices in DT with the c45
compatible.
