Jai Luthra 072f6348c5 ALSA: dmaengine: Synchronize dma channel after drop() 
[ Upstream commit e8343410ddf08fc36a9b9cc7c51a4e53a262d4c6 ]

Sometimes the stream may be stopped due to XRUN events, in which case
the userspace can call snd_pcm_drop() and snd_pcm_prepare() to stop and
start the stream again.

In these cases, we must wait for the DMA channel to synchronize before
marking the stream as prepared for playback, as the DMA channel gets
stopped by drop() without any synchronization. Make sure the ALSA core
synchronizes the DMA channel by adding a sync_stop() hook.
