ARM: dts: exynos: Cleanup HDMI DCC definitions on Exynos5250 and Exynos542x boards
Commit 2b7681326dc2 ("drm/exynos: hdmi: remove the i2c drivers and use") merged to v3.15 kernel added a required 'ddc' property to Exynos HDMI device tree bindings, which should point to i2c bus used for handling DDC (mainly reading display's EDID information). It has been enough time to convert all boards to use new bindings, but sadly due to copy/paste design the old approach using separate node with 'samsung,exynos4210-hdmiddc' compatible was used also for many new boards. This patch finally converts all boards to the new approach and unifies HDMI DDC definition across all Exynos boards.
