New config for Lenovo ThinkPad L390 i7-8565U

[bekliev]

Accordingly to this guideline for config files, I'm answering by their order:

1. This config is based on Lenovo U41-70.xml config file, cause of write and reads I think. Any other of ThinkPad line configs didn't work for my laptop.
2. Repeating: based on Lenovo U41-70.xml config.
3. This config doesn't require any modifications - just dropdown -> find it in the list -> Press Apply => and it will work.

Changes to base config:

1. Changed threshold of starting temperatures to be matched with system settings untill 68 degrees works as system fan set up. But from 68+ degrees fan set up to 85%, and after 90+ degrees set to 100%. Remark: system settings wasn't turn on the fan for even 85%, the max power was 72%.
2. Set fan's Min speed to 255 and Max speed to 64 - to be 100% matched with Current fan speed indicator. I mean Target fan speed and Current fan speed is identical with these settings.
3. Added CPU model to the config name, cause I thought it can cause different coolers - I don't know for sure.

Thank you very much for your effort.
I'd love to merge your pull request, but currently it doesn't pass all the unit tests:

Lenovo ThinkPad L390 i7-8565U config is not valid:

• All up-threshold values must be lower than the critical temperature
  --> At least one up-threshold is higher than or equal to the critical temperature: 100

Expected: True
Actual: False

Please fix this small issue and update the pull request, so I can merge it :)
