Hi Mark

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"
	> amixer set "MUX" "Input 2"

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

	> amixer set "MUX" "Label_A"
	> amixer set "MUX" "Label_B"

v3 -> v4
	- add missing property type

v2 -> v3
	- expand example on Doc

v1 -> v2
	- update git-log explanation
	- update property description
	- change property name "mux-names" -> "state-labels"
