Subject: [PATCH 1/2] dt-bindings: usb: Add chip-specific compatible string
 'fsl,ls-dwc3'

From: Ran Wang <ran.wang_1@....com>

Some Layerscape paltforms (such as LS1088A, LS2088A, etc) require update HW
default cache type configuration to fix DWC3 init failure when applying
property dma-coherent.

The cache type configuration is actually native feature of DWC3, not
additional desgin (or glue layer) coming from SoC, so add compatible string
'fsl,ls-dwc3'.
