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.
