First step is to add DMA_SLAVE_BUSWIDTH_3_BYTES to dma_slave_buswidth for
engines and users to select 3 bytes as bus width.
Followed by:
In dmaengine_pcm_set_runtime_hwparams() we should check the slave_caps of the
dma if it supports the give sample physical width of the sample. Based on this
information we initialize the hw.formats: masking out all non supported formats
based on the physical width.
In case the dma driver does not implement the slave_caps the default assumption
is that it supports 1, 2 and 4 bytes widths.
The whole series looks good to me. Since both the DMA and ALSA bits changed
in this series are fairly trivial I think it is best to merge the whole
series through the ASoC tree.
