Subject: [Patch v2 1/3] arm: exynos: Add new compatible string for
 Exynos3250 SoC.

Since,MFC v7 support was added for Exynos5420 and Exynos
3250 SoC with same compatible string "samsung,mfc-v7".As
both SoCs having different hardware properties and having
same compatible string for both SoCs doesn't seems to be correct.
New compatible is added for Exynos3250 SOC which will
differentiate the node properties for both SoCs which
support MFC v7.
