Subject: [PATCH] ASoC: soc-core: Set dpcm_playback / dpcm_capture

When converting a normal link to a DPCM link we need
to set dpcm_playback / dpcm_capture otherwise playback/capture
streams will not be created resulting in errors like this:

[   36.039111]  sai1-wm8960-hifi: ASoC: no backend playback stream

Fixes: a655de808cbde ("ASoC: core: Allow topology to override machine driver FE DAI link config")
