Performance events updates for v7.2:

Core perf code updates:

- Reveal PMU type in fdinfo (Chun-Tse Shao)

Intel CPU PMU driver updates:

- Fix various inaccurate hard-coded event configurations (Dapeng Mi)

Intel uncore PMU driver updates (Zide Chen):

- Fix discovery unit lookup bug for multi-die systems
- Guard against invalid box control address
- Fix PCI device refcount leak in UPI discovery
- Defer ADL global PMON enable to enable_box() to save power
- Fix uncore_die_to_cpu() for offline dies
- Implement global init callback for GNR uncore

AMD CPU PMU driver updates:

- Always use the NMI latency mitigation (Sandipan Das)

AMD uncore PMU driver updates:

- Use Node ID to identify DF and UMC domains (Sandipan Das)

Thanks,

Ingo
