media: dt-bindings: media: mediatek: Remove "dma-ranges" property for decoder 



Because the decoder nodes already make use of the iommus property to
configure the IOMMU for address translations, having a dma-ranges
property makes no sense.

In fact, after commit f1ad5338 ("of: Fix "dma-ranges" handling for
bus controllers"), having a dma-ranges property causes IOMMU faults.

Remove the dma-ranges property and update the example.
