[PATCH v3] mips: dts: ralink: mt7621: add cell count properties to usb

[Justin Swartz]

Add default #address-cells and #size-cells properties to the
usb node, which should be 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
