ASoC: dwc: don't assign addr_width for dt configs
For proper DMA operation addr_width must corresponds with audio format
(S16, S24, S32, etc). Proper bus width calculations is performed by
snd_hwparams_to_dma_slave_config(). So drop wrong addr_width asignment
for dt configs and let snd_hwparams_to_dma_slave_config() do the job.
