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.

Based on following:
9f3dbcb5632d (origin/queue, origin/6.9/scsi-queue, libsas-6.8) scsi:
csiostor: Avoid function pointer casts

  scsi: libsas: Add LIBSAS_SHT_BASE
  scsi: pm8001: Use LIBSAS_SHT_BASE
  scsi: hisi_sas: Use LIBSAS_SHT_BASE_NO_SLAVE_INIT
  scsi: aic94xx: Use LIBSAS_SHT_BASE
  scsi: mvsas: Use LIBSAS_SHT_BASE
  scsi: isci: Use LIBSAS_SHT_BASE
