dt-bindings: mediatek: Add binding for mt2712 IOMMU and SMI
This patch adds decriptions for mt2712 IOMMU and SMI.
In order to balance the bandwidth, mt2712 has two M4Us, two
smi-commons, 10 smi-larbs. and mt2712 is also MTK IOMMU gen2 which
uses ARM Short-Descriptor translation table format.
The mt2712 M4U-SMI HW diagram is as below:

All the connections are HW fixed, SW can NOT adjust it.
