dt-bindings: usb: snps,dwc3: Add missing 'dma-coherent' property
The 'unevaluatedProperties' schema checks is not fully working and doesn't catch some cases where there's a $ref to another schema. A fix is pending, but results in new warnings in examples. Some DWC3 implementations such as Xilinx are hooked up coherently and need to set the 'dma-coherent' property.
