Subject: [PATCH] dt-bindings: usb: dwc2: allow device sub-nodes

Allow the '#address-cells', '#size-cells' and subnodes as defined in
usb-hcd.yaml and used in the meson-gxbb-odroidc2 DT.

The fixes the following:
meson-gxbb-odroidc2.dtb: usb@...00000: '#address-cells', '#size-cells', 'hub@1' do not match any of the regexes: 'pinctrl-[0-9]+'
	from schema $id: http://devicetree.org/schemas/usb/dwc2.yaml#
