USB: gadget: Introduce ci13xxx_udc_driver struct
Introduces ci13xxx_udc_driver struct for bus glue drivers to hint ci13xxx_udc core about their special requirements. The flags include avoiding hardware register access when controller is not in peripheral mode, enabling pull-up upon VBUS, disabling streaming mode and dependency on transceiver driver. Initialize gadget_ops in udc_probe so that transceiver can notify VBUS presence even when no gadget driver is bounded. A notify_event callback is embedded in the same struct. This patch implements two events called CONTROLLER_RESET_EVENT and CONTROLLER_STOPPED_EVENT to notify the bus glue driver after resetting and stopping the controller for performing SoC specific quirks.
