If it does not exist, why even try to call socfpga_sgmii_config()?

It seems like this test needs moving up the call stack. socfpga_gen5_set_phy_mode():

	if (phymode == PHY_INTERFACE_MODE_SGMII)
		if (dwmac->sgmii_adapter_base)
			socfpga_sgmii_config(dwmac, true);
		else
			return -EINVAL;
			
Same in socfpga_gen10_set_phy_mode()?
