usb: dwc2: Add host/device hibernation functions
Add host/device hibernation functions which must be wrapped
by core's dwc2_enter_hibernation()/dwc2_exit_hibernation()
functions.
Make dwc2_backup_global_registers dwc2_restore_global_register
non-static to use them in both host/gadget sides.
Added function names:
dwc2_gadget_enter_hibernation()
dwc2_gadget_exit_hibernation()
dwc2_host_enter_hibernation()
dwc2_host_exit_hibernation()
