Current implementation brings support for BWMON v4, used for example

on SDM845 to measure bandwidth between CPU (gladiator_noc) and Last

|
Level Cache (memnoc). Usage of this BWMON allows to remove some of

the fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high

|
memory throughput even with lower CPU frequencies.
