Patch 1 wires up the previously-unused it6505 audio helpers via hdmi_codec_ops, which unblocks the mt8186-mt6366 sound card that references it6505 as the I2S3 codec. Patch 2 stops it6505_audio_setup_hw_params() from returning -ENODEV when no DP display is attached, which would otherwise tear down the shared backend and break playback on the co-located codec (the speaker). Tested on a MediaTek MT8186 (google,steelix) Chromebook: speaker and built-in mic work. Actual HDMI/DP audio output could not be tested as the sample exposes no usable DP-audio port.
