ASoC: remove snd_soc_dai_link_set_capabilities()

dpcm_xxx flags are no longer needed.

We need to use xxx_only flags instead if needed, but
snd_soc_dai_link_set_capabilities() user adds dpcm_xxx if playback/capture
were available. Thus converting dpcm_xxx to xxx_only is not needed.
Just remove it.
