perf/x86/intel/uncore: Support IIO free-running counters on DMR
The free-running counters for IIO uncore blocks on Diamond Rapids are
similar to Sapphire Rapids IMC freecounters, with the following
differences:
- The counters are MMIO based.
- Only a subset of IP blocks implement free-running counters:
HIOP0 (IP Base Addr: 2E7000h)
HIOP1 (IP Base Addr: 2EF000h)
HIOP3 (IP Base Addr: 2FF000h)
HIOP4 (IP Base Addr: 307000h)
- IMH2 (Secondary IMH) does not provide free-running counters.
