B4860QDS: Enable enet port as per fsl_b4860_serdes2 string in hwconfig
In B4860QDS board SerDes2 lanes EFGH either go to SFP or AMC riser card
slot2 so either DTSEC3/DTSEC4 or TGEC1/TGEC2 should be accessible. This
Patch enables DTSEC3/DTSEC4 or TGEC1/TGEC2 on bases of user specified
string fsl_b4860_serdes2:sfp_amc=amc or fsl_b4860_serdes2:sfp_amc=sfp
respectively in hwconfig.
