[PATCH v2 4/4] arm64: dts: mediatek: mt8195-demo: simplify mt6360 nodes

From: Macpaul Lin
Date: Wed Aug 30 2023 - 14:53:45 EST

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 common configuration of the MT6360 PMIC since
the included mt6360.dtsi is used.
- Add names according to the schematic of mt8195-demo board for
mt6360 nodes.
