coresight: platform: Cleanup coresight connection handling
The platform code parses the component connections and populates a platform-description of the output connections in arrays of fields (which is never freed). This is later copied in the coresight_register to a newly allocated area, represented by coresight_connection(s). This patch cleans up the code dealing with connections by making use of the "coresight_connection" structure right at the platform code and lets the generic driver simply re-use information provided by the platform. Thus making it reader friendly as well as avoiding the wastage of unused memory.
