FROMLIST: drm/display: add hw_params callback function to drm_connect…

…or_hdmi_audio_ops

After reusing drm_hdmi_audio_* helpers and drm_bridge_connector integration in drm/msm/dp, we have dropped msm_dp_audio_hw_params and use msm_dp_audio_prepare instead. While userspace is still calling hw_params to do audio initialization, and we get the following errors:

q6apm-lpass-dais 3700000.remoteproc:glink-edge:gpr:service@1:bedais: q6apm_lpass_dai_prepare() started

msm_dp_audio_prepare is not called because hdmi-codec driver only checks and runs hw_params before q6apm_lpass_dai_prepare(). This commit will add hw_params callback same as drm_connector_hdmi_audio_prepare, so that hdmi-codec driver can work with userspace alsa.

Tested with Radxa Dragon Q6A.
