Subject: [PATCH v5 1/3] dt-bindings: display: bcm2711-hdmi: Add interrupt
 details for BCM2712

Commit 62948c62abca ("dt-bindings: display: Add BCM2712 HDMI bindings")
added the compatible strings for BCM2712, but missed out that the
number of interrupts changed, and for BCM2712 the driver changes[1]
required that the interrupts are named.

Update the schema to correct the interrupt requirements for BCM2712.
(Requirements for BCM2711 should be unchanged).

[1] Commit 0b1dbe82e051 ("drm/vc4: hdmi: Add support for BCM2712 HDMI
controllers")

Fixes: 62948c62abca ("dt-bindings: display: Add BCM2712 HDMI bindings")
