Subject: [PATCH 9/9] coresight: Documenting reference to generic PD bindings

From: Mathieu Poirier <mathieu.poirier@...aro.org>

Each coresight block can be part of a power domain.  Using the
generic power domain subsystems to manage power to individual
domains guarantes that coresight operations won't be interrupted
by other components.
