Allow configuration for CPU max frequency

[Danielhp95]

Thanks for this really cool tool!

I did not see any documentation or issue where this, was mentioned. So here I go:

Is there a way to manually set, perhaps under /etc/auto-cpufreq.conf, a lower max frequency than the the default one?

For instance, having a max_frequency=1800 under the [battery] setting.

For context, my max frequency is rather high for me, and I would like to lower it.

Most welcome!

Regarding rest of your question, similar thing was request in #69. But this seems like a very interesting idea to have as part of config file.

If you feel like making this change yourself, please give it a try! Please make your changes and submit a pull request which I'll be glad to review. If your changes are accepted you'll be credited as part of releases page.

Just released v1.9.2 which adds ability to change power governor used by default with auto-cpufreq from balanced to performance using power_helper.py script which could also resolve this problem.

In meantime closing the issue due to inactivity, if the problem persist please feel free to re-open the issue.
