Subject: [PATCH v5 2/3] media: dt-bindings: media: mediatek: Remove "dma-ranges" property for decoder

Since commit f1ad5338a4d5 ("of: Fix "dma-ranges" handling for bus
controllers") was merge, we don't need a dma-ranges property for IOMMU
in mediatek video codec.

We remove the dma-ranges property and fix the example in
mediatek,vcodec-subdev-decoder.yaml
