This is targeting 22.11 and aims to add an API to DPDK power library to
allow uncore frequency adjustment. This will be called through the l3fwd-power
app and gives the ability to set the minimum and maximum uncore frequency to
both min, max or specific frequency index.

I did some edits to make it more comfortable to my eyes.
Applied, thanks.

I really would like 2 follow-ups please:
- some general clean-up in power library code and doc.
- some discussion about how we can make this library more generic.
