cs_topology_sysfs should discover CTI connections

[algrant-arm]

cs_topology_sysfs reads sysfs device nodes and discovers CoreSight devices and also ATB connections. Now that the CoreSight support in the kernel has been extended to support CTI (and CTI connections can be represented in the Device Tree), cs_topology_sysfs should discover those too.
