get_cpu_info() returns current frequency for both current and maximum frequency

[all-the-good-ones-are-gone]

In your bug report please include:

• CPU architecture AMD Ryzen 5 1600X Six-Core Processor
• Operating System openSUSE Tumbleweed 20180212 64bit / Linux 4.15.2-1-default
• Python version Python 2.7.14 (default, Oct 12 2017, 15:50:02) [GCC] on linux2
• Version of py-cpuinfo py-cpuinfo-3.3.0

Redirecting ticket here from downstream https://github.com/nicolargo/glances/issues/1233. When used in glances, values pulled for current CPU frequency and maximum CPU frequency are both current frequency, unlike when run on machines with i5-5600k and i7-2600k, but also happening on AMD FX(tm) - 6300.

Thanks for the bug report. Can you attache the "system_info.txt" generated by this script?

python tools/get_system_info.py

Thanks. I'll look more into this.

This might be a duplicate of #115 and might have been fixed in version 6.0.0. I no longer have access to a Ryzen CPU, so I cannot confirm that myself, but maybe @all-the-good-ones-are-gone can?
