Loosen the typec_mux_match() requirements so that searches where an alt mode is not specified, but the target mux device lists the "mode-switch" property, return a success. This is helpful in Type C port drivers which would like to get a pointer to the mux switch associated with a Type C port, but don't want to specify a particular alt mode.
