CRAS: apm_list - Construct channel layout that works with APM
For input device we could have two channels PCM with the first
channel unconnected. And that introduces a bug in APM use case
because APM processing only uses data in the first channel.
This change fixes the issue by always reconstruct a channel
layout that works with APM.
