net: stmmac: rk: rk3528: gmac0 only supports RMII
RK3528 gmac0 dtsi contains:
gmac0: ethernet@ffbd0000 {
phy-handle = <&rmii0_phy>;
phy-mode = "rmii";
mdio0: mdio {
rmii0_phy: ethernet-phy@2 {
phy-is-integrated;
};
};
};
This follows the same pattern as rk3328, where this gmac instance
only supports RMII. Disable RGMII in phylink's supported_interfaces
mask for this gmac instance.
