Microblaze: adapt for dma_map_ops changes
Adapt core Microblaze 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> [fixed coding style issues] Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de>
