Fix bad USB configuration under Developer Options

The USB configuration screen under Developer Options hasn't been
updated for the new USB access control changes. Update it.

1) Ensure that the default in Development Settings is "Charger Only".
2) Changing USB mode in developer settings only changes the USB function.
It doesn't unlock any USB data.
