I don't think there's such a thing as RMII delays. RMII has a single
clock, contrary to RGMII that has a TX and a RX clock with a 2ns delay
between clock and data.

I think it's just a leftover in this IP from the other variants that
can do RGMII ? You should just be able to drop the comment changes here,
and same goes for the dwmac patch.
