Subject: [PATCH 3/4] ASoC: SOF: compress: Save channel count and sample bytes

From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>

The purpose of this change is to enable the saving of the
channel count and sample container bytes format parameters for later use
to compute the timestamps.

This is done when setting the compress stream parameters
(in sof_compr_set_params).
