dt-bindings: gpu: Add V3D driver maintainer as DT maintainer

As established in commit 89d0499 ("MAINTAINERS: Drop Emma Anholt
from all M lines."), Emma is no longer active in the Linux kernel and
dropped the V3D maintainership. Therefore, remove Emma as one of the DT
maintainers and add the current V3D driver maintainer.
