[PATCH] drm/bridge: ite-it66121: Disable HDMI audio capture stream

[Sen Wang]

The IT66121 is an HDMI transmitter and does not support audio capture.
However, the driver registers hdmi-codec without setting no_i2s_capture,
causing the codec to advertise a non-functional capture stream. Userspace
audio servers such as PulseAudio then attempt to open this capture
device, resulting in errors.

Set no_i2s_capture and no_spdif_capture in hdmi_codec_pdata so that the
hdmi-codec driver only registers playback, matching the actual hardware
capability.
