When dr_mode is "otg" the dwc3 is initially configured in _OTG mode; However in this mode the gadget functionality doesn't work without further configuration. To resolve that on gadget start switch to _DEVICE mode globally and go back to _OTG on stop again.
For this the dwc3_set_mode is renamed to dwc3_core_set_mode to avoid a conflict with the same function exposed by xhci-dwc3
