[PATCH 3/6] arm64: dts: renesas: r8a774e1: Enable GPU

[Adam Ford]

The GPU on the RZ/G2H is a Rogue GX6650 which uses firmware
rogue_4.46.6.62_v1.fw available from Imagination.

When enumerated, it appears as:
 powervr fd00.gpu: [drm] loaded firmware powervr/rogue_4.46.6.62_v1.fw
 powervr fd00.gpu: [drm] FW version v1.0 (build 6513336 OS)
