Only some stmmac driver variants handle delays, dwmac-imx is not one
of them. it cares neither for phy-mode nor rx/tx-internal-delay-ps.
So I wouldn't mind putting instead
phy-mode = "rgmii-id";
rx-internal-delay-ps = <0>;
tx-internal-delay-ps = <0>;
with the same comment, as long as it is more correct.
