This look a bit 'lone wolf' here. Not sure how much time you intend to
spend on this, but FWIW, others prefer to declare all ports in the SoC
DTSI with status = "disabled", and just enable the ones used per-board,
and add labels and PHY handles also per-board. Example: fsl-ls1028a.dtsi
and fsl-ls1028a-rdb.dts.
