MIPS: adapt for dma_map_ops changes 

Adapt core MIPS architecture code for dma_map_ops changes: replace
alloc/free_coherent with generic alloc/free methods.

Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com>
Acked-by: Kyungmin Park <kyungmin.park@samsung.com>
[added missing changes to arch/mips/cavium-octeon/dma-octeon.c,
 fixed attrs argument in dma-mapping.h]
