[PATCH v2 2/4] ARM: dts: exynos: add a specific compatible to MCT

[Krzysztof Kozlowski]

One compatible is used for the Multi-Core Timer on most of the Samsung
Exynos SoCs, which is correct but not specific enough.  These MCT blocks
have different number of interrupts, so add a second specific
compatible to Exynos3250 and all Exynos5 SoCs.
