Subject: [PATCH v1 1/4] perf vendor events intel: Alderlake/rocketlake metric fixes

Fix that the core PMU is being specified for 2 uncore events. Specify
a PMU for the alderlake UNCORE_FREQ metric.

Conversion script updated in:
https://github.com/intel/perfmon/pull/126

Reported-by: Arnaldo Carvalho de Melo <acme@...nel.org>
Closes: https://lore.kernel.org/lkml/ZZWOdHXJJ_oecWwm@kernel.org/
