[PATCH] ASoC: samsung dma - prepare dma in start/resume trigger path

[Dylan Reid]

On suspend all dma transactions are terminated (by the stop/suspend
trigger calling ops->stop), they need to be set up again during resume.
Move the prepare op to the start/resume/unpause trigger path so that dma
and audio will restart on resume/unpause.
