Subject: [PATCH 1/3] arm64: exynos: Add new compatible string for Exynos3250
 SoC.

Exynos3250 uses the same compatible as Exynos5420, but both
the MFC IPs found in these SoC are different interms of clock
property. So using same compatible for both SoC is not correct.
Lets have a separate compatible for Exynos3250 and Exynos5420
to differentiate these SoCs.
