The current driver only supports a single HDMI controller, and part of the issue is that the main vc4_dev structure holds a pointer to its (only) HDMI controller, and the HDMI registers accessors will use it to retrieve the mapped addresses.
Let's modify those accessors to use directly the vc4_hdmi structure so that we can eventually get rid of that single global pointer.
