Changes done during conversion: 1. A typical (already used) properties like clocks, iommus and power-domains. 2. Require clocks, because they are essential for the block to operate. 3. Describe the differences in clocks between the Exynos5250/5420 and the Exynos5433 G-Scalers. This includes the fifth Exynos5433 clock "gsd" (GSCL Smart Deck) which was added to the DTS, but not to the bindings and Linux driver. Similarly to Exynos5433 DECON change [1], the clock should be used.
