intel-iommu: integrate DMA CMA
This adds support for the DMA Contiguous Memory Allocator for
intel-iommu. This change enables dma_alloc_coherent() to allocate big
contiguous memory.
It is achieved in the same way as nommu_dma_ops currently does, i.e.
trying to allocate memory by dma_alloc_from_contiguous() and
alloc_pages() is used as a fallback.
