arm: dma mapping: Export a dma ops function arm_dma_set_mask
Expose another DMA operations function: arm_dma_set_mask. This function will be added to a custom DMA ops for Armada 370/XP. Depending of its configuration Armada 370/XP can be set as a "nearly" coherent architecture. In this case the DMA ops is made of: - specific functions for this architecture - already exposed arm DMA related functions - the arm_dma_set_mask which was not exposed yet.
