* serdes bits and as RGMII via EC1_PMUX/EC2_PMUX bits
* Now if a dpmac is enabled as RGMII through ECx_PMUX then it takes
* precedence over SerDes protocol. i.e. in LX2160A if we select serdes
* protocol that configures dpmac17 as SGMII and set the EC1_PMUX as
* RGMII, then the dpmac is RGMII and not SGMII.
*
* Therefore, even thought fsl_rgmii_init is after fsl_serdes_init
* function of SOC, the dpmac will be enabled as RGMII even if it was
* also enabled before as SGMII. If ECx_PMUX is not configured for
* RGMII, DPMAC will remain configured as SGMII from fsl_serdes_init().
