Subject: [PATCH v8 1/2] dt-bindings: arm64: mediatek: add mt8395-evk board

1. Add compatible for MT8395.
2. Add bindings for the MediaTek mt8395-evk board, also known
as the "Genio 1200-EVK".

The MT8195 and MT8395 belong to the same SoC family,
with only minor differences in their physical characteristics.
They utilize unique efuse values for differentiation.

The booting process and configurations are managed by boot
loaders, firmware, and TF-A. Consequently, the part numbers
and procurement channels vary.
