dma: pl330: Set residue_granularity
The pl330 driver currently does not support residue reporting, so set the residue granularity to DMA_RESIDUE_GRANULARITY_DESCRIPTOR. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@linaro.org>
