usb: dwc3: of-simple: add a shutdown
In case we're loading a new kernel via kexec, let's make sure to cleanup the dwc3 address space correctly. This means that we should run the same steps from driver remove, so just extract a reusable function for both cases. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
