dt-bindings: mediatek: mt8188: Add binding for MM & INFRA IOMMU

Add descriptions for mt8188 IOMMU which also use ARM Short-Descriptor
translation table format.

In mt8188, there are two smi-common HW and IOMMU, one is for vdo(video
output), the other is for vpp(video processing pipe). They connects
with different smi-larbs, then some setting(larbid_remap) is different.
Differentiate them with the compatible string.

Something like this:

   IOMMU(VDO)          IOMMU(VPP)
      |                   |
 SMI_COMMON_VDO      SMI_COMMON_VPP
 ---------------     ----------------
  |     |    ...      |     |    ...
larb0 larb2  ...    larb1 larb3  ...

We also have an IOMMU that is for infra master like PCIe.
And infra master don't have the larb and ports.
