ASoC: davinci-pcm: fix audible glitch on 2nd ping-pong playback
The release of the dma channels was being performed in prepare and there was a edma_resume call for the asp-channel only being executed on START, RESUME and PAUSE_RELEASE. The mcasp on da850evm with ping-pong buffers enabled was exhibiting an audible glitch on every playback after the first. It was determined through trial and error that the following two changes fix this problem: 1) Move the edma_start calls from prepare to trigger and 2) reverse the order of starting the asp and ram channels.
