arm64: dts: exynos: Add GPU/Mali T760 node to Exynos7
Add nodes for GPU (Mali T760) to Exynos7. Current support for Exynos7 misses a lot, including proper clocks, power domains, frequency and voltage scaling and cooling. However this still can provide basic GPU description. Not tested on HW. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
