Systemd service for disabling smt on ppc64le compute nodes was added earlier. But the service is not enabled. So after reboot, smt is not getting disabled on ppc64le compute nodes. This patch adds code to enable the smt-disabling systemd service. Change-Id: I0b0371f97aa56a190cd6622b7ade739efc7c98f2
