scsi: define depopulation capabilities related service actions

Browse Source 
Add to include/scsi/scsi_proto.h the definition of the four service
actions of the SERVICE ACTION IN (16) command for the storage element
depopulation and restoration capabilities, as defined in the SBC5 and
ZBC2 specifications. These are:
 - SAI_GET_PHYSICAL_ELEMENT_STATUS (GET PHYSICAL ELEMENT STATUS command)
 - SAI_REMOVE_ELEMENT_AND_TRUNCATE (REMOVE ELEMENT AND TRUNCATE command)
 - SAI_RESTORE_ELEMENTS_AND_REBUILD (RESTORE ELEMENTS AND REBUILD command)
 - SAI_REMOVE_ELEMENT_AND_MODIFY_ZONES (REMOVE ELEMENT AND MODIFY ZONES
   command)

The physical element types and physical element health values reported by
the GET PHYSICAL ELEMENT STATUS command are also defined.
