[SCSI] pmcraid: support SMI-S object model of storage pool
PMC-Sierra mgmt application uses SMI-S model. According to SMI-S, the object model exposed by the SMI-S provider should show an StoragePool which contains member disks of a RAID Virtual disk and StorageVolume based on the StoragePool. But according to SMI-S, there is a possibility where StoragePool is created but StorageVolume is not yet created. To satisfy this scenario, we are trying a hidden RAID Virtual disk. The hidden RAID virtual disk will not be exposed to OS. Once a StorageVolume is created for this RAID virtual disk it is exposed.
