ASoC: omap-pcm: Select sDMA synchronization based on packet_size

Browse Source 
Since we only have element or packet synchronization we can use the
dma_data->packet_size to select the desired mode:
if packet_size is 0 we use ELEMENT mode
if packet_size is not 0 we use PACKET mode for sDMA synchronization.
