kernel: rtl8366-smi: add Realtek switch management via mii-bus

Browse Source 
Current version of rtl8366-smi module only supports Realtek switch
managment via two gpio lines. This adds Realtek switch
management via mii_bus. Tested on a Tp-link Archer C2 v1 (Mediatek
SoC mt7620a based)

dts-file configuration should look like this:

rtl8367rb {
	compatible = "realtek,rtl8367b";
	realtek,extif1 = <1 0 1 1 1 1 1 1 2>;
	mii-bus = <&mdio0>;
};

&ethernet {
	status = "okay";
	mtd-mac-address = <&rom 0xf100>;
	pinctrl-names = "default";
	pinctrl-0 = <&rgmii1_pins &rgmii2_pins &mdio_pins>;

	port@5 {
		status = "okay";
		mediatek,fixed-link = <1000 1 1 1>;
		phy-mode = "rgmii";
	};

	mdio0: mdio-bus {
		status = "okay";
	};
};
