drivers/usb/gadget.c: Add support for EHCI debug using the WCH CH347
The WCH CH347 presents a USB CDC serial port on interface 4 while in
operating modes 0, 1, and 3. Mode 0 also presents a UART on interface
2 but this is ignored for compatibility with the other modes. Mode 2
uses vendor defined HID usages for communication and is not currently
supported. Like the FT232H the data format is hard coded to 8n1.
Tested using a CH347 breakout board and a Dell Latitude E6400.
