[PATCH 0/2] usb: dwc2: Refactor and update USB DWC2 driver

[Kongyang Liu]

This series improves the USB DWC2 driver by extracting register definitions
into a common file for better readability and updating the reset method to
reflect changes in version 4.20a, including the new GRSTCTL_CSFTRST_DONE
bit for reset completion indication.
