coresight: fix cti gate enable disable apis functionalities 



Setting the CoreSight CTI Gate register enables CTI channel
propagation and clearing this register disables channel
propagation. Current implementation of CTI gate enable and
disable apis is not consistent with this channel propagation
behavior. Fix these api implementaions.
