drm/vc4: hdmi: Support BCM2711 CEC interrupt setup

Browse source

The HDMI controller found in the BCM2711 has an external interrupt
controller for the CEC and hotplug interrupt shared between the two
instances.

Let's add a variant flag to register a single interrupt handler and
deals with the interrupt handler setup, or two interrupt handlers
relying on an external irqchip.
