[SCSI] add supported_mode and active_mode attributes to the host
This adds supported_mode and active_mode attributes to /sys/class/sys_host/hostX/ for specifying the mode that a lld supports and the currently activated mode. The output format is similar to fc rport roles: luce:/sys/class/scsi_host/host0$ cat supported_mode Initiator luce:/sys/class/scsi_host/host0$ cat active_mode Initiator The mode values uses bitmap since we would support dual-mode llds in the future like this: luce:/sys/class/scsi_host/host0$ cat supported_mode Initiator, Target The supported_mode attribute looks at a scsi_host_template and the active_mode attribute looks at a scsi_host. We would add a hook to a scsi_host_template to change the active_mode attribute dynamically. But now there is no hook since no lld supports that feature.
