Subject: [PATCHv4 0/4] Add coresight support for SDM845 and MSM8996 

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

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

* Patch 2 adds device tree nodes for MSM8996 coresight components.

* Patch 3 enables support for ETMv4.2 and enables SDM845 to make
  use of same driver(etm4x).

* Patch 4 is a trivial removal of duplicate header file.

Patch 1 and 3 depends on below AOSS QMP patches by Bjorn:

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

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

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

 * 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.
