Commit a106804 ("ASoC: compress: Fix compress device direction check") added a dependency on the compress-cpu-dai channel_min field which was removed earlier by commit 77095796 ("ASoC: Intel: Atom: clean-up compressed DAI definition") as part of the baytrail cleanups.

The net result was a regression at probe on all Atom platforms with no sound card created.

Fix by adding explicit initialization for channel_min to 1 for the compress-cpu-dai.
