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.

Indeed, I missed broken checkpatch/DCO chain.

NAK. Please fix the chain.

Best regards,
