XHCI debug capability is actually a debug device gadget.
The hardware and firmware do everything of gadget work
and leave the interface to xHCI for enabling/disabling and
queuing transfer requests.
u_serial.c provides a generic layer between a USB gadget
and the TTY layer. I used it to avoid duplicating code.

Yes, you are right. Is it acceptable if I move u_serial.c from
the current place to drivers/usb/common?
