In preparation for adding a new driver for the HDMI TX v2 IP,
split out the functions that will be common between the already
present mtk_hdmi (v1) driver and the new one.
Since the probe flow for both drivers is 90% similar, add a common
probe function that will be called from each driver's .probe()
callback, avoiding lots of code duplication.
