coresight: add CoreSight core layer framework
CoreSight components are compliant with the ARM CoreSight architecture specification and can be connected in various topologies to suit a particular SoC tracing needs. These trace components can generally be classified as sources, links and sinks. Trace data produced by one or more sources flows through the intermediate links connecting the source to the currently selected sink. The CoreSight framework provides an interface for the CoreSight trace drivers to register themselves with. It's intended to build up a topological view of the CoreSight components and configure the correct serie of components on user input via sysfs. For eg., when enabling a source, the framework builds up a path consisting of all the components connecting the source to the currently selected sink(s) and enables all of them. The framework also supports switching between available sinks and provides status information to user space applications through the debugfs interface.
