ASoC: rsnd: enable DVC when capture 

Current DVC can be enabled only when playback,
but, this came from misunderstanding.
It is not correct.

DVC <-> DMA relationship is...

Playback: MEM -> DMAC  -> SRC -> DVC -> DMACp -> SSI
Capture:  SSI -> DMACp -> SRC -> DVC -> DMAC  -> MEM

DVC can be used for both Playback/Capture
