Subject: [PATCH v4 2/3] dt-bindings: display: Fix BCM2835 HVS bindings for
 BCM2712

Commit 6cfcbe548a3a ("dt-bindings: display: Add BCM2712 HVS bindings")
added the compatible string for BCM2712, but missed out that
the number of interrupts and clocks changed too, and both need to be
named.

Update to validate clock, interrupts, and their names for the variants.

Fixes: 6cfcbe548a3a ("dt-bindings: display: Add BCM2712 HVS bindings")
