arm64: dts: qcom: sdm845: Add CPU BWMON

Browse source

Add device node for CPU-memory BWMON device (bandwidth monitoring) on
SDM845 measuring bandwidth between CPU (gladiator_noc) and Last Level
Cache (memnoc).  Usage of this BWMON allows to remove fixed bandwidth
votes from cpufreq (CPU nodes) thus achieve high memory throughput even
with lower CPU frequencies.
