Subject: [PATCH 0/6] powercap: intel_rapl: Fixes and new platform enabling

Patch 1/6 fixes a real bug when MMIO RAPL driver is probed on platforms
that are not listed in current CPU model list. IMO, it should be
considered as stable material.

Patch 2/6 fixes a potential racing issue, but I have not reproduced it
yet.

Patch 3/6 ~ 4/6 fix a problem that TPMI RAPL driver probes disabled
System (Psys) RAPL Domains.

Patch 5/6 and 6/6 are two simple CPU model updates to support MSR RAPL
on Arrowlake and Lunarlake platforms.

thanks,
rui
