Just discussed this with Rakesh here at LPC and also with Mark Brown
and since earlier this years there's no a standard way to do this in
include/sound/hdmi-codec.h. I think it'd be good to port this over to
this new interface before merging. And if it makes sense (and ofc
afterwards when there's time) to port over the existing
i915_component.h to hdmi-codec.h.

Cheers, Daniel
