[SCSI] isci: T10 DIF support

This allows the controller to do WRITE_INSERT and READ_STRIP for SAS
disks that support protection information. SAS disks must be formatted
with protection information to use this feature via sg_format.

  sg3_utils-1.32 -- sg_format version 1.19 20110730
  sg_format usage:
  sg_format --format --verbose --pinfo /dev/sda
