ENGR00318773-5 ASoC: dmaengine: Merge trigger RESUME to START and SUSPEND to STOP

The SDMA driver doesn't support DMA_PAUSE and DMA_RESUME commands.
So this patch use TRIGGER_START for TRIGGER_RESUME and TRIGGER_SUSPEND
for TRIGGER_STOP as a work around so that Audio can normally stop
and restart its corresponding DMA channels.
