[PATCH v2 0/9] perf/cxlpmu: Misc sashiko raised issues fixes

[Dave Jiang <dave.jiang@intel.com>]

Teed off of Davidlohr's misc cxlpmu series [1]. I had Claude pick up all
the sashiko raised issues and then continued multiple internal review
iterations to pick up a number of fixes. I'm no CXL PMU or perf expert,
but the fixes look reasonable to me AFAICT.

Please give extra scrutiny to patch 3 and ensure the math is correct.

Since v1:
- Updated 3/9 to address sashiko issue.
- No other changes as sashiko only raised issue with pre-existing.
