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.

The patch set looks good to me.  If Mark can give an ack, I'll merge
them through my tree later.


thanks,

OK, thanks.  Now I applied all three patches to for-next branch.
