Use the common DAI DMA data struct for tegra, this allows us to use the common
helper function to configure the DMA slave config based on the DAI DMA data.

Would it make sense to have snd_dmaengine_pcm_set_config_from_dai_data()
call snd_soc_dai_get_dma_data() internally, to avoid all call-sites from
having to do it?

Yes, I thought about that as well, but there are some platforms like mmp
which we can't switch to using the generic DAI DMA data yet, but may find it
useful to be able to use this function. So they'd initialize the dma data
struct on the stack and pass it to the function.

Use the common DAI DMA data struct for fsl/imx, this allows us to use the common
helper function to configure the DMA slave config based on the DAI DMA data.

Use the common DAI DMA data struct for omap, this allows us to use the common
helper function to configure the DMA slave config based on the DAI DMA data.
For omap-dmic and omap-mcpdm also move the DMA data from a global variable to
the driver state struct.
