Instead of the OMAP DMA data type definition the data_type will be used to specify the number of bits the DMA word should be configured or 0 in case when based on the stream's format the omap-pcm can decide the needed DMA word size. This feature is needed for the omap-hdmi where the sDMA need to be configured for 32bit word type regardless of the audio format used.
