Subject: [Patch v4 3/3] ARM: dts: exynos: Add new SoC specific compatible
 string for Exynos3250 SoC

commit "752d3a23d1f68de87e3c" 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.
