armv8: fsl-layerscape: reorder rgmii dpmacs' enablement
some dpmacs in armv8a based freescale layerscape SOCs can be
configured via both serdes(sgmii, xfi, xlaui etc) bits and via
EC*_PMUX(rgmii) bits in RCW.
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 we select serdes protocol
that configures dpmac17 as SGMII and set the 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.
