drm/mediatek: mtk_hdmi: Move output init to mtk_hdmi_register_audio_driver()

In preparation for moving the common bits of this driver, merge the
contents of mtk_hdmi_output_init in mtk_hdmi_register_audio_driver
function to aggregate all of the initial audio setup together in
the same function and to make it clear that all of the setup that
is performed in mtk_hdmi_output_init is specifically related only
to audio and not video.
