[U-Boot] [REGRESSION] Ethernet broken on Colibri T20/T30

[Marcel Ziswiler]

Hi Simon

As mentioned before I noticed Ethernet (on-module USB ASIX chip) to be
broken on master while it still worked fine in v2016.01. I kind of
remember having once noticed something along those lines when testing
some of your early dm stuff but could not find our discussion about it
anymore plus I don't think it did actually lead anywhere.

FWIW it currently crashes as follows (showing Colibri T20 but the same
happens on Colibri T30):

Do you have any clue what could be going on?
