Merge patch series "Add LIBSAS_SHT_BASE for libsas"

Browse Source 
John Garry <john.g.garry@oracle.com> says:

There is much duplication in the scsi_host_template structure for the
drivers which use libsas.

Similar to how a standard template is used in libata with
__ATA_BASE_SHT, create a standard template in LIBSAS_SHT_BASE.
