ARM: dts: exynos: Add GPU/Mali 400 node to Exynos3250
Add nodes for GPU (Mali 400) to Exynos3250. This is still limited and not tested: 1. No dynamic voltage and frequency scaling, 2. Not sure what to do with CLK_G3D clock responsible for gating entire IP block (it is now being disabled as unused). Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
