[PATCHv3 1/4] arm64: dts: qcom: sdm845: Add Coresight support

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

Add coresight components found on Qualcomm SDM845 SoC.

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

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