Someone have posted a good patch for that device:
http://www.right.com.cn/forum/thread-157588-1-1.html
The dts above works fine.
After applying the patch above,you need to edit the following:
		reset {
			label = "reset";
			gpios = <&gpio1 6 0>;
			linux,code = <0x198>;
		};
change 0x198 to 0x100
and add the mt76 section in
	pcie at 10140000 {
		status = "okay";
	};


BTW ,the mac address is defined here:
	ethernet at 10100000 {
		pinctrl-names = "default";
		pinctrl-0 = <&ephy_pins>;
		mtd-mac-address = <&factory 0x4>;   <----------
		ralink,port-map = "llllw";
	};
