add SPI transport class to fusion

So for channel=0, for all target_ids equal to pIocPg3->PhysDisk[].PhysDiskID, then vdev->vtarget->tflags equal to MPT_TARGET_FLAGS_RAID_COMPONENT , and we set sdev->no_uld_attach = 1. For non-raided devices on this channel, we set sdev->no_uld_attach = 0. All queue_command request for hidden devices with tflags set for RAID_COMPONENT, will be sent with function=MPI_FUNCTION_SCSI_IO_REQUEST.
