ASoC: simple-audio-mux: enable to select MUX names

Browse source

simple-audio-mux is designed to be used generally, thus "Input 1" or
"Input 2" are used to selecting MUX input. This numbered inputs would
work, but might be not user friendly in some case, for example in case
of system hardware design has some clear labels.
Adds new "state-labels" property and enable to select MUX by own state
names.

Original
	> amixer set "MUX" "Input 1"

Use mux-names
	sound_mux: mux {
		compatible = "simple-audio-mux";
		mux-gpios = <...>;
		state-labels = "Label_A", "Label_B";
	};

	> amixer set "MUX" "Label_A"
