> Add the "samsung,snps-dwc3" compatible string to dwc3-generic-plat so the
> Exynos8855 USB3 DWC3 controller can probe through the generic DWC3
> platform glue. 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.
