The bump to 4.14 changed the way mdio probes behind switches. While the board_info is added to the list, the code that actually inserted the list info into the phydev structure was missing. This resulted in non-working ethernet ports. Re-add it to fix switch probing. This mimics the exact behaviour as it was in kernel 4.9.
