net: phy: atheros: Fix problem with phy_reset() clearing BMCR
In commit <a058052c358c> [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.
