Subject: [PATCH] powercap: intel_rapl_msr: Add PL4 support for PantherLake

Add PantherLake to the list of processors where PL4 is supported.

Signed-off-by: Zhang Rui <rui.zhang@...el.com>

The PL4 support for Arrowlake-S and Lunarlake are also missing for now.
We will add them later when there is a real need. I'm also checking
internally to see if it is required or not.
