ASoC: SPEAr: get rid of spear-pcm-audio struct device Modify the SPEAr PCM driver so that it's a utility library that can be registered on each DAI, rather than a separate struct device. This is more in line with how many recent DT-converted platforms operate, and avoids the need for yet another struct device. This is also required as a pre-cursor to removing spear_pcm_request_chan(). Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>

ASoC: SPEAr: remove custom DMA alloc compat function spear_pcm_request_chan() is almost identical to dmaengine_pcm_compat_request_channel(), with the exception that the latter: a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data pointer rather than some custom type. b) dma_data->filter_data rather than dma_data should be passed to snd_dmaengine_pcm_request_channel() as the filter data. Make minor changes to the SPEAr DAI drivers so that those two conditions are met. This allows removal of the custom .compat_request_channel().
