DMA-API: dma: pl330: add dma_set_mask_and_coherent() call
The DMA API requires drivers to call the appropriate dma_set_mask() functions before doing any DMA mapping. Add this required call to the AMBA PL330 driver. Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
