Since the existing DT-nodes will be renamed in a subsequent patch let's fix the DWC3 Qcom-specific code to detect the DWC3 sub-node just by checking its compatible string to match the "snps,dwc3". The semantic of the code won't change seeing all the DWC USB3 nodes are supposed to have the compatible property with any of those strings set.
