Subject: [PATCH] usb: dwc3: gadget: increase timeout value for send ep cmd
In case the USB3 PHY enters P3, then ep command may need a long
time to complete, per test of ep0out enable, the dwc3 trace time
stamp shows the time is more then 280us, so increase the timeout
loop count to be 2000, this has no side effect for HW which has
no this problem.
