> e.g. dpmac 17 and 18 in LX2160A can be configured as SGMII from serdes bits
> and as RGMII via EC1_PMUX/EC2_PMUX bits Now if a dpmac is enabled by
> serdes bits then it takes precedence over EC*_PMUX bits. i.e. in LX2160A if

> EC1_PMUX as RGMII, then the dpmac is SGMII and not RGMII.

> Therefore, move the fsl_rgmii_init after fsl_serdes_init. in fsl_rgmii_init
> function of SOC, we will check if the dpmac is enabled or not? if it is
> (fsl_serdes_init has already enabled the dpmac), then don't enable it.
