[PATCHv7 0/6] Add coresight support for SDM845, MSM8998 and MSM8996

[Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org>]

This patch series adds support for coresight on SDM845, MSM8998, and MSM8996.

* Patch 1 adds device tree nodes for SDM845 coresight components.

* Patch 2 adds device tree nodes for MSM8998 coresight components.

* Patch 3 adds device tree nodes for MSM8996 coresight components.

* Patch 4 enables support for ETMv4.2 and enables SDM845 to make
  use of same driver(etm4x).

* Patch 5 adds ETM PIDs for SDM845 and MSM8996.

* Patch 6 adds coresight CPU debug module for Qualcomm Kryo.

Patch 5 and 6 depends on UCI support by Mike Leach:
 * https://lore.kernel.org/lkml/20190130234051.2294-1-mike.leach@linaro.org/ 

This patch series has been tested on SDM845 MTP and MSM8996
based Dragonboard 820c and MSM8998 MTP.

v7:
 * Change uci_id_debug struct to const.
 * Update the subject as suggested by Suzuki.

v6:
 * Update the UCI table with the new macro introduced by
   Mike.
 * Rebase on top of coresight-next and provide a tree with
   all the dependent patches applied.

v5:
 * Added coresight support for MSM8998.
 * Added ETM PIDs for SDM845 and MSM8996 as suggested
   by Suzuki.
 * Added UCI table for Coresight CPU debug module.

v4:
 * Mask out the minor version as suggested by Mathieu.
 * Added the dependent patch description in patch 1.

v3:
 * Added arm,scatter-gather property as suggested by Suzuki.

v2:
 * Added coresight support for msm8996 based on Vivek's patch.
   Cleaned up and added coresight cpu debug nodes for msm8996.
 * Merged coresight dtsi file into sdm845.dtsi as suggested by Bjorn
 * Addressed Mathieu's feedback about masking the minor version in
   etm4_arch_supported() and added a comment for reason to bypass
   the AMBA bus discovery method.
