Subject: [PATCH 0/3] Mediatek Genio EVKs: add MT6359 PMIC keys support

This patchset adds the support of the MT6359 PMIC keys (Power and Home)
that can be found on the Mediatek Genio 510, 700 and 1200 EVK boards
by:
- adding the MT6359 SoC support in the mtk-pmic-keys driver
- completing the existing definitions (only the Power key
  support was present) in Genio 510/700 EVK board common
  devicetree include file (mt8390-genio-common.dtsi)
- add the needed definitions in Genio 1200 EVK board devicetree
  (mt8395-genio-1200-evk.dts)

I've tested this patchset on Mediatek Genio 1200-EVK board with a
kernel based on linux-next (tag: next-20250703) plus [1] patch.
