On the Qcom platforms making use of DWC3 IP, xhci IRQs are received after
some delay while resuming from runtime suspend. Due to this, the xhci
driver once resumed, quickly goes into runtime suspend mode again, thus
deferring the usb enumeration.

So let's add a 200ms autosuspend delay to the xhci driver so that it get's
enough time to catch the IRQs.
