ALSA: x86: Allow single period PCM operation This is an implementation of PCM streaming with only 1 period. Since the hardware requires the refresh of BDs after each BD processing finishes, we'd need at least two BDs. The trick is that both BDs point to the same content: the address of the PCM buffer head, and the whole buffer size. Then it loops over to the whole buffer again after it finished once.
