net: phy: LAN87xx: remove genphy_softreset in config_aneg

When the T1 phy master/slave state is changed, at the end of config_aneg
function genphy_softreset is called. After the reset all the registers
configured during the config_init are restored to default value.
To avoid this, removed the genphy_softreset call.
