ar71xx: fix switch probing on kernel 4.14
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.
Before:
[ 1.066007] switch0: Atheros AR8327 rev. 4 switch registered on ag71xx-mdio.0
[ 1.073409] Atheros AR8216/AR8236/AR8316: probe of ag71xx-mdio.0:00 failed with error -22
