net: stmmac: qcom-ethqos: move qcom_ethqos_set_sgmii_loopback() up
ethqos_set_func_clk_en() configures both SGMII loopback and the RGMII
functional clock setting. qcom_ethqos_set_sgmii_loopback() is only
called from within ethqos_set_func_clk_en(), and checks for
PHY_INTERFACE_MODE_2500BASEX.
Move qcom_ethqos_set_sgmii_loopback() to the callers of
ethqos_set_func_clk_en() except for ethqos_configure_rgmii() where we
know that ethqos->phy_mode will not be PHY_INTERFACE_MODE_2500BASEX.
