iommu: Add set_platform_dma_ops callbacks
For those IOMMU drivers that don't provide default domain support, add an
implementation of set_platform_dma_ops callback so that the IOMMU core
could return the DMA control to platform DMA ops. At the same time, with
the set_platform_dma_ops implemented, there is no need for detach_dev.
Remove it to avoid dead code.
