Bug 419598

SUMMARY
Ksysguard shows wrong CPU frequency from Ryzen 7 3700X

OBSERVED RESULT
Because Ksysguard reads the CPU speed from /proc/cpuinfo, the maximum frequency is always displayed. Wich makes this sensor useless. I'm not sure 


If Ksysguard would read the frequency from /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq
it would display correct values, and at the same time the average values would be displayed as nice integers.

EXPECTED RESULT
Correct values for CPU frequencies
