Merge tag 'mtk-soc-for-v6.20' of https://git.kernel.org/pub/scm/linux/kernel/git/mediatek/linux into soc/drivers

MediaTek soc driver updates

This adds:
 - A socinfo entry for the MT8371 Genio 520 SoC
 - Support for the Dynamic Voltage and Frequency Scaling
   Resource Controller (DVFSRC) version 4, found in the
   new MediaTek Kompanio Ultra (MT8196) SoC
 - Initial support for the CMDQ mailbox found in the MT8196.
 - A memory leak fix in the MediaTek SVS driver's debug ops.
