Fabio Estevam d584c68ce0 phy: atheros: Use ar8035_config for AR8031
Commit 08ad9b068a (" ar8031: modify the config func of ar8031 to
ar8021_config") selected 'ar8021_config' as the configuration function
for AR8031.

The correct would be to use 'ar8035_config' instead as AR8031/AR8035
have the same programming model and even share the same phy driver
in the linux kernel: drivers/net/phy/at803x.c.

Tested on a mx6qsabresd and wandboard, which now can work without
any PHY setup code in the board files.
