[PATCH net-next v2 20/22] net: stmmac: rk: rk3528: gmac0 only supports RMII

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

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.
