In preparation for adding a driver for the HDMIv2 IP and before
moving the common bits out of this driver, add a new structure
`mtk_hdmi_ver_conf`, holding pointers to HDMI IP version specific
drm_bridge_funcs, hdmi_codec_ops and clock array used for probe,
and nest it into the mtk_hdmi_conf platform data structure.

While at it, also convert all of the direct users of
mtk_hdmi_bridge_funcs, mtk_hdmi_audio_codec_ops, mtk_hdmi_clk_names
to use pointers from the ver_conf platform data.

In order to do so, it was also necessary to fill a new version 1
specific const `mtk_hdmi_v1_ver_conf` and assign it to all of the
currently supported compatibles for this driver.

This commit brings no functional change.
