dt-bindings: usb: dwc2: switch to unevaluatedProperties

Define "unevaluatedProperties" instead of "additionalProperties"
to allow properties from common schemas but still disallow undefined
properties.

This allow defining a device subnode and fixes:
meson-gxbb-odroidc2.dtb: usb@c9100000: '#address-cells', '#size-cells', 'hub@1' do not match any of the regexes: 'p
inctrl-[0-9]+'
        from schema $id: http://devicetree.org/schemas/usb/dwc2.yaml#

Fixes: bb88dbbee2 ("dt-bindings: usb: dwc2: Add reference to usb-drd.yaml")
Fixes: 54bd6c9a3b ("dt-bindings: usb: dwc2: document TPL support")
