I don't think that is the correct patch. Yes, it broke here, but that
was a different problem. 

I think the real commit is:
6d4cd041f0af ("net: phy: at803x: disable delay only for RGMII mode")

That commit contains a fix for broken behaviour in the PHY driver,
when then also causes broken DTs to fail.
