[PATCH v1 1/2] dt-bindings: usb: gpio-sbu-mux: Make 'enable-gpios' optional

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx>

The enable gpio is not required when the SBU mux is used only for
orientation, make enable-gpios required only for alternate mode
switch use case.
