[PATCH v3 07/18] arm64: dts: mediatek: mt8192: Add GPU nodes

[AngeloGioacchino Del Regno]

From: Alyssa Rosenzweig <alyssa.rosenzweig at collabora.com>

The MediaTek MT8192 includes a Mali-G57 GPU supported in Panfrost. Add
the GPU node to the device tree to enable 3D acceleration.

The GPU node is disabled by default. It should be enabled by board with
its power supplies correctly assigned.
