ARM: dts: Update DP controller DT Node for Exynos5 based SoCs

Moves the properties of DP controller to exynos5.dtsi which are common
across exynos5 SoCs like Exynos5250 and Exynos5420.

The PHY DP Node is based on Jingoo Han's <jg1.han@samsung.com> patch
at https://patchwork.linuxtv.org/patch/19189/Signed-off-by: Vikas Sajjan <vikas.sajjan@linaro.org>
