perf/x86/amd/uncore: Add PerfMonV2 RDPMC assignments

mainline inclusion
from mainline-v6.0-rc1
commit f0fe9f3c
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5YLE2


CVE: NA

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

The current RDPMC assignment scheme maps four DF PMCs and
six L3 PMCs from index 6 to 15.

If AMD Performance Monitoring Version 2 (PerfMonV2) is
supported, there may be additional DF counters available
which are mapped starting from index 16 i.e. just after
the L3 counters. Update the RDPMC assignments accordingly.
