USB: ci13xxx_udc: Convert ATDTW loop into finite one

Currently while queueing requests to HW, waiting in infinite
loop till ATDTW bit set for HW semaphore to be released by HW
to avoid race conditions between HW and SW. This could lead to
watchdog timer expiry if bus infrastructure is stuck. Hence
convert this loop into finite loop of 100msec which is atmost
required for USB HW to release HW semaphore as per HW team.
