USB: gadget: Implement hardware queuing in ci13xxx_udc

Chipidea USB controller provides a means (Add dTD TripWire semaphore)
for safely adding a new dTD to an active endpoint's linked list.  Make
use of this feature to improve performance.  Dynamically allocate and
free dTD for supporting zero length packet termination.  Honor
no_interrupt flag set by gadget drivers.
