ARM: dts: exynos: Fix G3D power domain supply on Odroid XU3/XU4/HC1 boards
G3D power domain in Exynos5422 SoC is supplied from VDD_G3D. Besides the
main GPU MALI module it also contains the power domain control logic and
clocks. Turning the VDD_G3D power supply off causes the power domain to
fail to operate properly and breaks for example system suspend/resume.
GPU should use VDD_G3D supply mainly to control the DVFS.
