!2541 Intel: Backport some SPR and EMR PMU related upstream bugfixes to OLK-5.10
Merge Pull Request from: @yunyingsun Title: Backport some SPR and EMR PMU related upstream bugfixes to OLK-5.10 Content: There're some PMU related upstream bugfixes that are needed for SPR and EMR: (v6.1-rc4) 0916886b perf/x86/intel: Fix pebs event constraints for SPR (v6.4-rc4) 38776cc4 perf/x86/uncore: Correct the number of CHAs on SPR (v6.6-rc1) 6f7f984f perf/x86/uncore: Correct the number of CHAs on EMR They corrected the number of CHAs on SPR and EMR, also updated the PEBS event constraints for SPR. The 3 backported patches are identical in code changes comparing to the original commit. Intel-kernel issue: #I8AR40:Backport some SPR and EMR PMU related upstream bugfixes to OLK-5.10 Test: Without these backported patches, the number of "/sys/devices/uncore_cha_*" devices on SPR and EMR is wrong. For example, with kernel that has included 38776cc4 but not having 6f7f984f, there's no /sys/devices/uncore_cha_* devices on EMR. With these applied, the number of uncore_cha_* devices will be correct for SPR and EMR.
