dt-bindings: usb: add missed compatible string for arm64 layerscape 



Add missed compatible string for arm64 layerscape platform. Allow these
fallback to fsl,ls1028a-dwc3.

Remove fallback snps,dwc3 because layerscape dwc3 is not full compatible
with common snps,dwc3 device, a special value gsburstcfg0 need be set when
dma coherence enabled.

Allow iommus property.

Change ref to snps,dwc3-common.yaml to use dwc3 flatten library.
