ASoC: SOF: Intel: only support INFO_BATCH for legacy platforms

The current position update is not precise enough for PulseAudio to work reliably, so disable the NO_PERIOD_WAKEUP capability and use BATCH to signal that the pistion is only reliabe and updated during period_elapsed events. This will be reverted when the firmware provides a more accurate position. Signed-off-by: Pierre-Louis Bossart <[email protected]>
