From: Alexander Stein <alexander.stein@mailbox.org>

commit 640f35b871d29cd685ce0ea0762636381beeb98a upstream.

This property was already mentioned in the old textual bindings
amlogic,meson-vpu.txt, but got dropped during conversion.
Adding it back similar to amlogic,gx-vdec.yaml.

Fixes: 6b9ebf1e0e67 ("dt-bindings: display: amlogic, meson-vpu: convert to yaml")
