Patch 1 adds the ETM UCI IDs for Kryo 4XX CPU cores. Patch 2 adds the DT nodes for coresight components on SC7180. Patch 3 replaces ETM PIDs with UCI IDs for Kryo385 CPUs on SDM845.

v2:
* Placed the DT properties for ports in one line as suggested by Stephen.
* Add UCI IDs for SC7180 and SDM845(Kryo385 CPUs) as suggested by Suzuki.
