Add mt8188 smi supporting in the bindings.

In mt8188, there are two smi-common HW, one is for vdo(video output),
the other is for vpp(video processing pipe). They connect with different
smi-larbs, then some setting(bus_sel) 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  ...
