("dt-bindings: display: bridge: it6505: Add #sound-dai-cells").

Patches 1-11 fix pre-existing bugs found during review of earlier
versions of this series; they carry Fixes: tags and are ordered first
so stable trees can pick them.

Patch 12 wires up the it6505 audio helpers via hdmi_codec_ops,
unblocking the mt8186-mt6366 sound card which references it6505 as
the I2S3 codec. Patch 13 makes hw_params succeed with no display
attached, needed when the I2S bus is shared with another codec as on
MT8186 "steelix" Chromebooks, where the speaker path must keep
working regardless of the it6505 link state.

Tested on a MT8186 (google,steelix) Chromebook: the sound card comes
up, speakers, microphone and headset jack work. HDMI/DP audio output
itself could not be tested for lack of a suitable adapter cable.

Whole series is
