8e8edc6401 x86: move dma_coherent functions to pci-dma.c
They are placed in an ifdef, since they are i386 specific
the structure definition goes to dma-mapping.h.

fae9a0d8ca x86: merge iommu initialization parameters
we merge the iommu initialization parameters in pci-dma.c
Nice thing, that both architectures at least recognize the same
parameters.

usedac i386 parameter is marked for deprecation

sure i386 keeps with the same behaviour it used to.

802c1f6648 x86: move dma_supported and dma_set_mask to pci-dma_32.c
This is the way x86_64 does, so this make them equal. They have
to be extern now in the header, and the extern definition is moved to
the common dma-mapping.h header.

4d92fbf231 x86: move dma_map_page and dma_unmap_page to common header
They are similar enough to do this move.
the macro version is ugly, and we use inline functions instead.

That's already the name of the game for x86_64. For i386,
we add a pci-base_32.c, that will hold the default operations.
