[PATCH 4/4] arm64: dts: mediatek: mt8195-demo: simplify mt6360 nodes

The dts file for the MediaTek MT8195 demo board has been refactored
to improve the configuration of the MT6360 multi-function PMIC.

The changes include:
 - Addition of the mt6360.dtsi include file, which contains the common
   configuration of the MT6360 for all mt8195 boards.
 - Removal of the direct inclusion of the mt6360-regulator.h file.
 - Removal of the detailed configuration of the MT6360 PMIC since
   the included mt6360.dtsi is used.
