Maybe the third time's a charm :)
This cleans up some DMA-API documentation and makes a minor no-op change to
the dma_declare_coherent_memory() prototype.
Changes from v2:
- Added description of CPU virtual/physical and bus addresses in
DMA-API-HOWTO
- Added comments to sh/PCI (Dreamcast) update
- Dropped IOMMU interface dma_addr_t changes
I didn't add Arnd's and Greg's acks to patch 1 because of all the new
address description text I added.

sh/PCI: Pass GAPSPCI_DMA_BASE CPU & bus address to dma_declare_coherent_memory()
iommu/exynos: Remove unnecessary "&" from function pointers
