ALSA: hda - Disable audio component for legacy Nvidia HDMI codecs
The old Nvidia chips have multiple HD-audio codecs on the same HD-audio controller, and this doesn't work as expected with the current audio component binding that is implemented under the one-codec-per- controller assumption; at the probe time, the driver leads to several kernel WARNING messages. For the proper support, we may change the pin2port and port2pin to traverse the codec list per the given pin number, but this needs more development and testing. As a quick workaround, instead, this patch drops the binding in the audio side for these legacy chips since the audio component support in nouveau graphics driver is still not merged (hence it's basically unused).
