Intel IronLake and ValleyView platforms have different HDMI widget pin and digital port mapping from other newer ones. The recent ones (HSW+) have NID 0x05 to 0x07 for port B to port D, while these chips have NID 0x04 to 0x06.
For adapting this mapping, pass the codec object instead of the bus object to snd_hdac_sync_audio_rate() and snd_hdac_acomp_get_eld() so that they can check the codec ID and calculate the mapping properly.
The changes in the HDMI codec driver side will follow in the later patch.
