So now we get to the bottom of it. This is a regression, right? The
addition of that patch has caused previously working boards to stop
working, correct?

We also need to get out of our heads the idea that LAN8710A is somehow
special in needing this. It isn't. Thus, there should be no special
flags to "work around" this "problem".
