[PATCH v2 4/8] arm64: dts: mediatek: mt8188: Add SMI/LARB/IOMMU support

From: Fei Shao
Date: Wed Sep 11 2024 - 06:54:05 EST

Local Arbiter (LARB) is a component of Smart Multimedia Interface (SMI)
that supports IOMMU on the MediaTek SoCs.

Add the following nodes for memory management support on MT8188 SoC:
- one Infra IOMMU
- two Multimedia (MM) IOMMUs of VDO and VPP
- corresponding SMI common and LARB nodes of the MM IOMMUs
