Since commit 59370f3fcd1350 ("net: phy: delay only if reset handler is registered") Ethernet is no longer functional:
Booting from net ... FEC Waiting for PHY auto negotiation to complete......... TIMEOUT ! BOOTP broadcast 1 BOOTP broadcast 2 BOOTP broadcast 3 BOOTP broadcast 4
This commit does not have an issue in itself, but it revelead a problem with the Ethernet initialization.
Configure the AR8035 PHY in the same manner as done in mx6sabresd and wandboard, so that we can get a reliable Ethernet operation.
