While at it, alphabetically reorder the existing entries. The "samsung,snps-dwc3" string is used as a generic fallback to support any Exynos SoC that utilizes a flattened model instantiation. This fallback allows multiple Exynos SoCs to be supported by the generic platform driver simply by adding the fallback compatible to their respective device tree nodes.
