Subject: [PATCH v1 03/32] perf vendor events intel: Refresh alderlake-n metrics
Update the alderlake-n metrics using the new tooling from:
https://github.com/intel/perfmon
The metrics are unchanged but the formulas differ due to parentheses,
use of exponents and removal of redundant operations like "* 1".
