Integrate the generic dma remapping implementation into the main flow. This prepares for architectures like xtensa that use an uncached segment for pages in the kernel mapping, but can also remap highmem from CMA. To simplify that implementation we now always deduct the page from the physical address via the DMA address instead of the virtual address. Signed-off-by:
