Add genphy_config_aneg() method to phy::Device, wrapping the C function __genphy_config_aneg(). This is needed by PHY drivers that perform custom BMCR configuration before calling the generic auto-negotiation setup. The wrapper calls __genphy_config_aneg(phydev, false) directly since genphy_config_aneg() is a static inline function not visible to bindgen.
