media: dt-bindings: media: mtk-vcodec: Add dma-ranges property
The mt8192 iommu support 0~16GB iova. We separate it to four banks:
0~4G; 4G~8G; 8G~12G; 12G~16G.
The "dma-ranges" could be used to adjust the bank we locate.
If we don't set this property. The default range always is 0~4G.
This is optional and only needed in mt8192, the dma ranges should
not cross 4G/8G/12G.
Here we don't have actual bus/parent concept here. And the iova
requirement is for our HW. Thus put the property in our node.
