dma-mapping fixes for Linux 4.21-rc1

Fix various regressions introduced in this cycles:

 - fix dma-debug tracking for the map_page / map_single consolidatation
 - properly stub out DMA mapping symbols for !HAS_DMA builds to avoid
   link failures
 - fix AMD Gart direct mappings
 - setup the dma address for no kernel mappings using the remap
   allocator
