In accordance with the USB HCD/DRD schema all the USB controllers are supposed to have DT-nodes named with prefix "^usb(@.*)?". Since the existing DT-nodes will be renamed in a subsequent patch let's first make sure the DWC3 Qualcomm driver supports them and second falls back to the deprecated naming so not to fail on the legacy DTS-files passed to the newer kernels.
