Description

Print the CPU frequency correctly without privileges. Some CPU's have two clusters and at the same time are not representatives of the "Big.Little" architecture. It will be correct to print about the presence of adjustment of two clusters

How Has This Been Tested?

Before the changes:

leo@bananapim3:~$ armbianmonitor -m 1
Running unprivileged. CPU frequency will not be displayed.
Stop monitoring using [ctrl]-[c]
Warning: High update frequency (1 sec) might change system behaviour!

Time       big.LITTLE   load %cpu %sys %usr %nice %io %irq   CPU  C.St.

After:

leo@bananapim3:~$ armbianmonitor -m 1
Two CPU clusters are available for monitoring
