Use SBE_UPDATE_CONSECUTIVE functionality for P9 Machines

  - If an update is necessary for the primary SBE SEEPROM (side 0), it will
      be updated.  After the update, a re-IPL is requested and the reboot
      count will be set to the default so side 0 is used to boot.  If during
      the re-IPL an update is necessary for the backup SBE SEEPROM (side 1),
      it will be updated and the IPL is allowed to continue. The end result
      is that both SBE SEEPROMs will contain the same code.
