Sorry, this doesn't work. We updated the binding, the backend must
be a phandle to the partition which contains the state data, like
this:

backend = <&mmc1_state>;

&mmc1 {
	mmc1_state: state at 0x80000 {
		reg = <0x80000 0x80000>;
                label = "state-sd";
	};
};

Currently it is not possible to directly point to a DOS/GPR partition. We
are still looking for solutions to this problem.
