CMY 862c97fb02 rk: dma-mapping: Add support DMA allocate memory without mapping
reserved DMA(CMA) regions may be large than 512MB for devices, placed it
in the highmem zone is appropriate, but according to the existing
mechanism, memory allocation with mapping will cause vmalloc area not
enough.

Now we don't do mapping if the DMA_ATTR_NO_KERNEL_MAPPING is set.
