The iommu-dma layer is now mostly encapsulated by iommu_dma_ops, with
only a couple more public interfaces left pertaining to MSI integration.
Since these depend on the main IOMMU API header anyway, move their
declarations there, taking the opportunity to update the half-baked
comments to proper kerneldoc along the way.

Note that iommu_setup_dma_ops() should also become internal in a future
phase of the great IOMMU API upheaval - for now as the last bit of true
arch code glue I consider it more "necessarily exposed" than "public".
