[PATCH 6/6] arm64: dts: renesas: r8a77961: Enable GPU

[Adam Ford]

The GPU on the R-Car M3-W+ is a Rogue GX6250 which uses firmware
rogue_4.45.2.58_v1.fw available from Imagination.

When enumerated, it appears as:
powervr fd00.gpu: [drm] loaded firmware powervr/rogue_4.45.2.58_v1.fw
powervr fd00.gpu: [drm] FW version v1.0 (build 6513336 OS)
