Incorrect frequency reporting for Intel 12th gen CPUs

[xtenduke]

Current source of CPU frequency /sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq is unsuitable for modern CPUs, specifically heterogeneous CPUs like Intels 12th gen.

Attached example shows an i7 12800h running at idle.

I think it would be better if we changed this to the highest clock speed reported across all cores.
Cores with the MAXMHZ of 3700 are E-cores and have a lower turbo clock sped.

Now the frequency of each core is monitored and the highest value is taken.
