[PATCH v3 15/33] drm/mediatek: mtk_hdmi: Disgregate function mtk_hdmi_audio_set_param()

[AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxx>]

As a cleanup, and in preparation for splitting common bits of this
driver, disgregate the code in function mtk_hdmi_audio_set_param()
between mtk_hdmi_audio_params() and mtk_hdmi_audio_hw_params().

The generic hdmi_audio_param copy now gets performed in the former,
and the IP specific mtk_hdmi_aud_output_config() gets called in the
latter, allowing all of the non IP version specific code to get
moved in a common file later.
