drm/vc4: hdmi: Introduce resource init and variant
The HDMI controllers found in the BCM2711 has a pretty different clock and registers areas than found in the older BCM283x SoCs. Let's create a variant structure to store the various adjustments we'll need later on, and a function to get the resources needed for one particular version.
