arm: dts: at91: remove unused #address-cells/#size-cells from sam9x60 udc node

The UDC node does not define any child nodes, so the "#address-cells" and
"#size-cells" properties are unnecessary. Remove these unused properties
to simplify the devicetree node and keep it consistent with DT conventions.
