Yes, I do.  We are moving to device tree, so the Kconfig symbol
IMX_HAVE_PLATFORM_FEC makes no sense any more, as the platform device
registration will be done by DT core according whether there is a FEC

No.  By doing that, FEC will not be selected for any SoCs by default.
You need to select it explicitly if you are building a platform with
FEC support.
