ASoC: Intel: Clear stored Baytrail DSP DMA pointer before stream start

Browse Source 
Stored DSP DMA pointer must be cleared before starting the stream since
PCM pointer callback sst_byt_pcm_pointer() can be called before pointer is
updated. In that case last position of previous stream was wronly returned.
