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.
