Subject: [PATCH v3 10/33] drm/mediatek: mtk_hdmi: Convert to module_platform_driver macro

Now that all of the mtk_hdmi subdrivers are a platform driver on
their own it is possible to remove the custom init/exit functions
in this driver and just use the module_platform_driver() macro.

While at it, also compress struct of_device_id entries and remove
stray commas in mtk_hdmi_driver assignments.
