dt-bindings: usb: genesys,gl850g: allow downstream device subnodes

As this binding describes USB hubs, it's natural for them to have
downstream devices.

Change "additionalProperties" to "unevaluatedProperties" to allow
properties defined in usb-device.yaml (for DT cells properties) and add
a pattern-based downstream device subnode rule to match those subnodes.

These changes allow downstream devices get defined under the hub.
