[PATCH v3 1/3] dt-bindings: usb: mediatek,mtk-xhci: Add port for SuperSpeed EP

[AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>]

Add a port used to connect the SuperSpeed output endpoint to a
Type-C connector.

Note that the MediaTek XHCI controllers are always in front of a
different controller handling the USB HS (usually, MTU3), so the
only port that this controller provides is SuperSpeed, while the
HighSpeed one comes from elsewhere.
