As established in the previous commit, using SPEED_1000 and SPEED_2500 does not make sense for a SerDes due to the PCS encoding that is used over the SerDes link, which inflates the data rate at the SerDes. Thus, the use of these constants in a SerDes driver is incorrect. Since qcom-sgmii-eth no longer implements phy_set_speed(), but instead uses the PHY interface mode passed via the .set_mode() method, convert the driver to use the PHY interface mode internally to decide whether to configure the SerDes for 1.25Gbps or 3.125Gbps mode.
