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