    The commit 889ad3b "usb: musb: try a race-free wakeup" breaks device
    hotplug enumeraitonn when the device is connected behind a hub while usb
    autosuspend is enabled.
    
    Adding finish_resume_work into runtime resume callback fixes the issue.
    
    Also resume root hub is required to resume the bus from runtime suspend,
    so move musb_host_resume_root_hub() back to its original location, where
    handles RESUME interrupt.
