net: phy: atheros: Fix problem with phy_reset() clearing BMCR

In commit <a058052c> [net: phy: do not read configuration register on
reset], phy_reset() will clear the BMCR register. Bit 12(AUTO_NEGOTIATION)
is cleared too. It causes auto-negotiation timeout error on Atheros's
PHY AR8033.

To fix this problem, genphy_config_aneg() and genphy_restart_aneg()
needs to be called in ar8035_config() to enable and restart
auto-negotiation.
