This is in the wrong place. It is a MAC property. You usually put it
next to phy-handle.

+            };
+            eth_phy1: ethernet-phy@1 {
+                reg = <1>;
+                phy-mode = "rmii";
+            };
+        };

I would suggest you structure this differently to make it clear it is
a two port switch:

	ethernet-ports {
		#address-cells = <1>;
                #size-cells = <0>;

                port@0 {
                    reg = <0>;
		    phy-handle = <&eth_phy0>;
		    phy-mode = "rmii";
		}

		port@1 {
                    reg = <1>;
		    phy-handle = <&eth_phy1>;
		    phy-mode = "rmii";
		}
	}
