of/device: Update dma_range_map only when dev has valid dma-ranges
The commit e0d072782c73 ("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset") always update dma_range_map even though it was already set, like in the sunxi_mbus driver. the issue is reported at [1]. This patch avoid this(Updating it only when dev has valid dma-ranges). Meanwhile, dma_range_map contains the devices' dma_ranges information, This patch moves dma_range_map before of_iommu_configure. The iommu driver may need to know the dma_address requirements of its iommu consumer devices.
