  1. updateInterface: enable hot-add nic on arm64

    For now, update interface in agent will fail when hot-add
    nic to a running containers on arm64 as rescan pci bus will
    occur between uf and bf of shpc hotplug interrupt handling.
    
    Another problem is that the rootBusPath will be
    "/devices/platform/4010000000.pcie/pci0000:00" on arm64.
    
    To enable hot-add nic on arm64, rootBusPath should be changed here
    and shpc hotplug should be disabled in guest kernel.
    
    This patch just change rootBusPath.
