coresight: adding basic support for Vexpress TC2
Support for the 2 PTMs, 3 ETMs, funnel, TPIU and replicator connected to the ETB are included. Proper handling of the ITM and the replicator linked to it along with the CTIs and SWO are not included. Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org>
