[PATCH 08/12] dt-bindings: usb: vialab,vl817: allow ports property

[Icenowy Zheng]

As a USB hub device, VL817 can surely be connected to external USB
connectors. The binding for such connectors connection is already
described in the generic usb-hub.yaml binding with ports subnode, but
it's not yet allowed in the VL817 binding.

Switch the reference binding from usb-device.yaml to usb-hub.yaml (which
recursively references usb-device.yaml and contains definition for ports
subnode) and allow ports subnode in VL817 binding.
