[PATCH 2/2] dt-bindings: usb: genesys,gl850g: add downstream facing ports

[Dmitry Baryshkov]

In order to describe connections between Genesys GL850G hub and
corresponding Type-C connectors, follow example of RTS5411 and describe
downstream facing ports. Unline normal case of ports being connected to
a USB device, hotplug ports use OF graph representation.
