topology: increase number of periods for low latency pipeline 

Increases number of periods for low latency playback pipeline
from 1 to 2 for volume and mixer components. 1 period
is not good enough to have continuous DMA transfer across
the whole pipeline, especially with the new copy flow,
which requires playback pipeline preload.
