If you did it, you would see here that the binding does not work and needs fixes... The difference between your DTS and your example should also warn you that it's not correct.

RZ/N1 SoC includes two MAC named GMACx that are compatible with the "snps,dwmac" driver. GMAC1 is connected directly to the MII converter port 1. Since this MII converter is represented using a PCS driver, it uses the renesas specific compatible driver which uses this PCS.
