[PATCH v7 01/14] dt-bindings: media: mediatek,vcodec: Remove dma-ranges property

[Yong Wu]

After commit f1ad5338a4d5 ("of: Fix "dma-ranges" handling for bus
controllers"), the dma-ranges of the leaf node doesn't work. Remove
it for vcodec here.

For mediatek,vcodec-decoder.yaml and mediatek,vcodec-encoder.yaml,
this property is in the leaf node, it is invalid as the above comment.

Currently there is only mt8195 VENC node has this property in upstream.
Indeed, VENC is affected, but it is not a fatal issue. Originally it
expects its iova range locate at 4GB-8GB. However after that commit, its
expectation doesn't come true, it will fall back to 0-4GB iova and also
could work well.
