AR8035/phy: Enable autonegotiation function for ar8035

Function "genphy_parse_link()" used "if (mii_reg & BMSR_ANEGCAPABLE)" before,
but used "if (phydev->supported & SUPPORTED_Autoneg)" now.
So assign "phydev->supported" to "phydev->drv->features" for ar8035
to enable autonegotiation. Then removed the genphy_config_aneg() function.
