Precedence: bulk

Add coresight components found on Qualcomm SDM845 SoC.

Signed-off-by: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org>

---
Depends on AOSS QMP side channel patches and AMBA bus pclk change
by Bjorn Andersson [1][2].
Also depends on patch ("arm64: dts: qcom: sdm845: Increase address
and size cells for soc") [3].
