From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Stash the ELD into the crtc_state and precompute it. This gets
rid of the ugly ELD mutation during intel_audio_codec_enable(),
and opens the door for the state checker.
v2: Make another copy for the acomp hooks (Chaitanya)
Split out the bogus ELD handling change (Jani)
