Subject: [PATCH] perf/x86/rapl: Add support for Intel Arrow Lake U

Add Arrow Lake U model for RAPL.

  $ ls -1 /sys/devices/power/events/
energy-cores
energy-cores.scale
energy-cores.unit
energy-gpu
energy-gpu.scale
energy-gpu.unit
energy-pkg
energy-pkg.scale
energy-pkg.unit
energy-psys
energy-psys.scale

The same output as ArrowLake.
  $ perf stat -a -I 1000 --per-socket -e power/energy-pkg/
