> This commit fixes an issue in the power library
> related to using lcores mapped to different
> physical cores (--lcores option in EAL).
> 
> Previously, the power library incorrectly accessed
> CPU sysfs attributes for power management, treating
> lcore IDs as CPU IDs.
> e.g. with --lcores '1 at 128', lcore_id '1' was interpreted
> as CPU_id instead of '128'.
> 
> This patch corrects the cpu_id based on lcore and CPU
> mappings. It also constraints power management support
> for lcores mapped to multiple physical cores/threads.
> 
> When multiple lcores are mapped to the same physical core,
> invoking frequency scaling APIs on any lcore will apply the
> changes effectively.
> 
> v2:
>  - renamed check_lcore_and_set_cpu to power_get_lcore_mapped_cpu_id
