Seppo Ingalsuo d58e733c7b Topology: Change 16kHz DMIC DAI into 32bit mode and make scheduling 1ms
This patch changes the secondary DMIC FIFO configuration into 32 bits
mode for better quality. Since there is volume component in DMIC
capture pipelines the conversion to other PCM formats can happen
there. Using volume controller with 32 bit input gives a lot better
audio quality when the microphone signal needs amplification.

The scheduling of 16 kHz DAI is changed to 1000us. The comment
of 1000 us is correct but the parameter 48 is not. With 16 frames
the scheduling becomes the desired. This change should also save
some RAM due to smaller buffers.
