We suspect this particular commit introduces this bug, the sample app will not work with the -U -u and -i options.

The options worked when I tried with 23.07. I also tried removing this commit and the options worked again.

power: refactor uncore power management API

Currently the uncore power management implementation is vendor specific.

Added new vendor agnostic uncore power interface similar to rte_power and rename specific implementations ("rte_power_intel_uncore") to "power_intel_uncore" along with functions.
