          This option enables full functionality of MSM_PERFORMANCE for

          QGKI flavor. This is not defined in GKI builds wherein the driver

          offers minimal functionality of changing the min and max frequency

          of a given cluster. The user space can request  the cpu freq change

          by writing cpu#:freq values
