usb: dwc2: Refactor backup/restore of registers
The DWC2 runtime PM code reuses similar patterns to backup and
restore the registers. So consolidate them in USB mode specific
variants. This also has the advantage it is reusable for further
PM improvements.
Special care is taken for DCFG register during device mode restore.
