iommu/mediatek: Improve safety for mediatek,smi property in larb nodes
No functional change. Just improve safety from dts.
All the larbs that connect to one IOMMU must connect with the same
smi-common. This patch checks all the mediatek,smi property for each
larb, If their mediatek,smi are different, it will return fails.
Also avoid there is no available smi-larb nodes.
