Turns off CoreSight CTI save and restore support for cpu CTIs. This
avoids voting for the clocks during probe as well as the associated
save and restore latency at the cost of breaking cpu CTI support on
targets where cpu CTIs have to be preserved across power collapse.
If unsure, say 'N' here to avoid breaking cpu CTI support.
