arm64: dts: rockchip: add Coresight debug range for RK3399

Browse Source 
Per Documentation/devicetree/bindings/arm/coresight-cpu-debug.txt.

This IP block can be used for sampling the PC of any given CPU, which is
useful in certain panic scenarios where you can't get the CPU to stop
cleanly (e.g., hard lockup).
