net: stmmac: qcom-ethqos: remove unnecessary setting max_speed

Phylink will already limit the MAC speed according to the interface,
so if 2500BASE-X is selected, the maximum speed will be 2.5G. It is,
therefore, not necessary to set a speed limit. Remove setting
plat_dat->max_speed from this glue driver.
