ASoC: ux500_pcm: Stop pretending that we support varying address widths
The Slave Config's addr_width attribute is populated by data_width of dma_cfg, which in turn is derived from dma_params' data_size attribute and that comes from the slot_width which is always 16 bits (2 Bytes). We're cutting out the middle man here and just setting the DMA Slave Config directly. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>
