cpufreq: qcom-hw: use no_log when reading cpu counter val

Browse source 
Use the no_log version of readl_relaxed when reading out the
counter values for CPUs to reduce the amount of logging in
RTB Logs. Scheduler activity is very frequent and clogs up the
buffer, which can potentially reduce the amount of useful logs.
