After commit f1ad5338a4 ("of: Fix "dma-ranges" handling for bus
controllers"), the dma-ranges of the leaf node doesn't work. Remove
it for jpeg here.
Currently there is only mt8195 jpeg node has this property in upstream,
and it already uses parent-child node, this property did work. But instead,
MediaTek iommu will control the masters' iova ranges by the master's
larb/port id internally, then this property is unnecessary.
