Commit 62948c62abca ("dt-bindings: display: Add BCM2712 HDMI bindings")
added the compatible strings for BCM2712, but missed out that the
number of interrupts changed with the "wakeup" interrupt not present in
the BCM7212.
Update the schema to correct the interrupt requirements for BCM2712.
(Requirements for BCM2711 should be unchanged).
