Commit 5441e9dafdfc6dc40 ("[media] s5p-mfc: Core support for MFC v7")
which adds mfc v7 support for Exynos3250 and use the same compatible
string as used by Exynos5240 but both the IPs are a bit different in
terms of IP clock.
Add variant driver data based on the new compatible string 
"samsung,exynos3250-mfc" for Exynos3250 SoC.
