net: phylink: fix SGMII inband autoneg enable
When we are operating in SGMII inband mode, it implies that there is a PHY connected, and the ethtool advertisement for autoneg applies to the PHY, not the SGMII link. When in 1000base-X mode, then this applies to the 802.3z link and needs to be applied to the PCS. Fix this.
