ASoC: soc-pcm: dpcm: fix playback/capture checks 

Recent changes in the ASoC core prevent multi-cpu BE dailinks from
being used. DPCM does support multi-cpu DAIs for BE Dailinks, but not
for FE.

Handle the FE checks first, and make sure all DAIs support the same
capabilities within the same dailink.
