Here's the 2nd iteration of the patch to improve link management granularity between controllers using HDA extended bus and HDA codec drivers. Based on feedback to V1, this now adds a new link_power op. This allows to decouple HDA codec drivers from the hdac_ext core. I also included two patches to SOF to show how this interface is used in SOF.
