perf/x86/amd/core: Detect available counters

mainline inclusion
from mainline-v5.19
commit 56e026a7
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5S3WV


CVE: NA

-------------------------------------------------

If AMD Performance Monitoring Version 2 (PerfMonV2) is
supported, use CPUID leaf 0x80000022 EBX to detect the
number of Core PMCs. This offers more flexibility if the
counts change in later processor families.
