    libpayload: usb: Reset ohci controller when trying to shutdown ohci
    
    Currently we just disabled ohci interrupts when calling ohci_shutdown,
    Which would not actually shutdown the ohci controller, for example it
    may still written the increased HccaFrameNumber to Hcca buffer.
    
    Perform a soft reset to ohci controller as the linux kernel ohci-hcd
    driver does.
    
    BUG=chrome-os-partner:60996
    BRANCH=None
    TEST=Checked on gru, no more "BUG: Bad page state" error in kernel.
