Cezary Rojewski Feb. 18, 2020, 2:39 p.m. UTC
Declare extraction CPU DAI as well as sof_probe_compr_ops. FE DAIs can
link against these new CPU DAI to create new compress devices.

Signed-off-by: Cezary Rojewski <cezary.rojewski@intel.com>

Changes in v4:
- Relocated probe-compress related code from /sof/pcm.c directly to
  /sof/compress.c as requested by Daniel
