usb: dwc3: gadget: Keep track of IRQ timing statistics
It may be useful to debug how much time is spent in the
DWC3 hard IRQ context. Add low-overhead statistics counters
which keep a histogram of the last 10 interrupts' time of
occurence, time spent, and number of events read (which will
get processed in the bottom half handler).
