ALSA: hda - Fix conflict of sticky PCM parameter in HDMI codecs
Intel and Nvidia HDMI codec drivers have own implementations of sticky PCM parameters. Now HD-audio core part already has it, thus both setups conflict. The fix is simply remove the part in patch_intelhdmi.c and patch_nvhdmi.c and simply call snd_hda_codec_setup_stream() as usual.
