[SCSI] mpt fusion: RAID device handling and Dual port Raid support is added
1. Handle integrated Raid device(Add/Delete) and error condition and check related to Raid device. is_logical_volume will represent logical volume device. 2. Raid device dual port support is added. Main functions to support this feature are mpt_raid_phys_disk_get_num_paths and mpt_raid_phys_disk_pg1.
