arm64: Replace set_arch_dma_coherent_ops with arch_setup_dma_ops

Commit a3a60f81ee6f (dma-mapping: replace set_arch_dma_coherent_ops with
arch_setup_dma_ops) changes the of_dma_configure() arch dma_ops callback
to arch_setup_dma_ops but only the arch/arm code is updated. Subsequent
commit 97890ba9289c (dma-mapping: detect and configure IOMMU in
of_dma_configure) changes the arch_setup_dma_ops() prototype further to
handle iommu. The patch makes the corresponding arm64 changes.
