dt-bindings: memory: mediatek: Add mt8195 smi binding
Add mt8195 smi supporting in the bindings.
In mt8195, 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
