[ Upstream commit 68a9b0e313302451468c0b0eda53c383fa51a8f4 ]
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 energy-psys.unit
The same output as ArrowLake:
$ perf stat -a -I 1000 --per-socket -e power/energy-pkg/
