dmaengine: consolidate memcpy apis

Browse source

Copying from page to page (dma_async_memcpy_pg_to_pg) is the superset,
make the other two apis use that one in preparation for providing a
common dma unmap implementation.  The common implementation just wants
to assume all buffers are mapped with dma_map_page().
