The Linux Kernel topology sysfs is flawed.
core_id is not globally unique, but is per-package.
Turbostat works around this when it needs to, with
rapl_core_id = cpus[cpu].core_id;
rapl_core_id += cpus[cpu].package_id * nr_cores_per_package
Otherwise, turbostat handles core_id as subservient to each package.
As there is only one core_id namespace, rename
physical_core_id to simply be core_id.
No functional change.
