ASoC: dt-bindings: simple-mux: add idle-state property 



simple-mux immediately activates the new output, even when it is powered
down. This can be undesirable in some cases, for example when a
mechanical relais is used.
Adds "idle-state" property from the mux controller to select the output
state to be used when the mux is powered down.
