DT-binding of reg-mux is defined in such a way that one need to provide register offset and mask in a "mux-reg-masks" property and corresponding register value in "idle-states" property. This constraint forces to define these values in such a way that "mux-reg-masks" and "idle-states" must be in sync with each other. This implementation would be more complex if specific register or set of registers need to be configured which has large memory space. Introduce a new property "mux-reg-masks-state" which allow to specify offset, mask and value as a tuple in a single property.
