perf/x86/intel/uncore: Expose an Uncore unit to IIO PMON mapping
Current version supports a server line starting Intel® Xeon® Processor
Scalable Family and introduces mapping for IIO Uncore units only.
Other units can be added on demand.
IIO stack to PMON mapping is exposed through:
/sys/devices/uncore_iio_<pmu_idx>/dieX
where dieX is file which holds "Segment:Root Bus" for PCIe root port,
which can be monitored by that IIO PMON block.
Details are explained in Documentation/ABI/testing/sysfs-devices-mapping
