Commit a1068045883ed4a18363a4ebad0c3d55e473b716 added a dependency on the compress-cpu-dai channel_min field which was removed earlier by commit 77095796ae9cbaf315f80611edb5aa569796e339 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.
