RFC 6/7 dt-bindings: usb: typec-mux: Add property for default mux mode

For some devices it is necessary to specify a different initial mux mode to use after connection. E.g. some devices may not have USB SS support but just USB HS and an alternate mode and thus prefer TYPEC_MUX_NONE as default mode.
