[PATCH 8/9 v2] coresight: adding basic support for Vexpress TC2

[mathieu.poirier at linaro.org]

From: Mathieu Poirier <mathieu.poirier at linaro.org>

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.
