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). Since that commit
separate node with "samsung,exynos4210-hdmiddc" compatible is no longer
needed, so mark it finally as deprecated.
