[PATCH] coresight: Add support for Juno platform

[Mathieu Poirier <mathieu.poirier-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

This patch adds support for ARM's juno platform.  More
specifically it has definitions for the A53/57 tracers, the
A53/57 cluster funnels, the main funnel and the ETF in
circular buffer mode.

Support for the replicator, TPIU, ETR, CTI, CTM, ATM along with
all the coresight IP blocks found in the SPC sub-system have
not been addressed.
