[PATCH v5] arm64: dts: qcom: Add msm8916 CoreSight components

[Georgi Djakov <georgi.djakov-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

From: "Ivan T. Ivanov" <ivan.ivanov-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

Add initial set of CoreSight components found on Qualcomm msm8916 and
apq8016 based platforms, including the DragonBoard 410c board.

Changes since v4: (https://lkml.org/lkml/2016/11/17/533)
 * Move everything into the SoC dtsi file as suggested by Stephen Boyd.
 * Updated commit message.
 * Got Ack from Mathieu.

Changes since v3: (https://lkml.org/lkml/2015/5/11/134)
 * Include msm8916-coresight.dtsi into msm8916.dtsi

Changes since v2: (https://lkml.org/lkml/2015/4/29/242)
 * Added "1x" to "qcom,coresight-replicator" compatible string, to match what
   devicetree bindings documentations says.
