[PATCH 3/3] arm64: dts: exynos: add a specific compatible to MCT

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 Exynos5433 and Exynos850.
