USB: gadget: composite device-level suspend/resume hooks
Address one open question in the composite gadget framework: Yes, we should have device-level suspend/resume callbacks in addition to the function-level ones. We have at least one scenario (with gadget zero in OTG test mode) that's awkward to handle without it.
