Since MFC v7 support was present for both Exynos5420 and Exynos3250 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. Add new compatible for Exynos3250 SoC followed by mfc-v7 fallback which will differentiate the node properties for both SoCs which support MFC v7.
