The new IbexPeak HDMI codec has 3 pin nodes and 2 converter nodes.
Here we assume only the first ones will be used.

Comparing with v1, the only change is the rename of codec from "P55"
to "Q57". The dynamic data structure will be introduced by future
patches.
OK, applied now.
Thank you!

The needed change would be pretty easy, just change cvt_nid to
spec->cvt_nid, etc...
Ah OK. I'll put the members into intel_hdmi_spec instead of the
planned hda_codec.
Thanks,
Fengguang
