    USB: add RESET_RESUME for webcams shown to be quirky

    The new runtime PM code has shown that many webcams suffer
    from a race condition that may crash them upon resume.
    Runtime PM is especially prone to show the problem because
    it retains power to the cameras at all times. However
    system suspension may also crash the devices and retain
    power to the devices.
    The only way to solve this problem without races is in
    usbcore with the RESET_RESUME quirk.
