Kdump support dump to raw device which could be on top of complex storage
such as multipath and iscsi which are standalone dracut modules.
Add a --device option to dracut which will add the device to host_devs so
dracut can add the dependent modules automaticlly and enable them in initramfs.
--device will accept device node name as the param.
