I've seen similar errors on other boards when the phy is not powered or 
does not have a clock supplied. Could you check your DT if there is any 
diffs in the phy-supply or any gpio-Hog pulling the enable of a 
regulator that might enable the phy? Also you could check if you have 
all the required regulator drivers available and probed.

Best regards
Johannes
