[PATCH] dt-bindings: usb: Add missing properties used in examples

[Rob Herring <robh@xxxxxxxxxx>]

With 'unevaluatedProperties' support implemented, the following warnings
are generated in the usb examples:

Documentation/devicetree/bindings/usb/intel,keembay-dwc3.example.dt.yaml: usb: usb@34000000: Unevaluated properties are not allowed ('reg' was unexpected)
Documentation/devicetree/bindings/usb/snps,dwc3.example.dt.yaml: usb@4a030000: Unevaluated properties are not allowed ('reg' was unexpected)

Add the missing property definitions.
