[PATCH] mips: dts: ralink: mt7621: add cell count properties to usb0

[Justin Swartz <justin.swartz@xxxxxxxxxxxxxxxx>]

Add default #address-cells and #size-cells properties to usb0,
suitable for hubs and devices without explicitly declared
interface nodes, as:

  "#address-cells":
    description: should be 1 for hub nodes with device nodes,
      should be 2 for device nodes with interface nodes.
    enum: [1, 2]

  "#size-cells":
    const: 0

-- from Documentation/devicetree/bindings/usb/usb-device.yaml
