Subject: [Patch v5 3/3] ARM: dts: exynos: Add new SoC specific compatible
 string for Exynos3250 SoC

Commit 752d3a23d1f68de ("ARM: dts: add MFC codec device node for
exynos3250") which adds MFC codec device node for exynos3250 SoC.
Since exynos3250.dtsi and exynos5420.dtsi are using same compatible
string as "samsung,mfc-v7" but their node properties are different.
As both SoCs have MFC v7 hardware module but with different clock 
hierarchy and complexity.
Add new compatible string followed by mfc-v7 fallback for Exynos3250
SoC.
