dt-bindings: mediatek: Add bindings for MT6779
This patch adds description for MT6779 IOMMU.
MT6779 has two iommus, they are mm_iommu and apu_iommu which
both use ARM Short-Descriptor translation format.
In addition, mm_iommu and apu_iommu are two independent HW instance
, we need to set them separately.
The MT6779 IOMMU hardware diagram is as below, it is only a brief
diagram about iommu, it don't focus on the part of smi_larb, so
I don't describe the smi_larb detailedly.
