ASoC: dmaengine: Use filter_data rather than dma_data for compat requests
When using the legacy filter function channel requests we currently pass the audio specific struct snd_dmaengine_dai_dma_data which isn't likely to be helpful for actual filtering. Since there's already a field in the structure called filter_data clearly intended for use here convert the driver to use that. All existing users of plain filter functions have been converted to use an explicit compat function to override this behaviour except i.MX which is working around this issue in its filter function and is updated to just use filter_data directly here.
