Most of the Samsung Exynos SoCs use almost the same Multi-Core Timer block, so only two compatibles were used so far (for Exynos4210 and Exynos4412 flavors) with Exynos4210-one being used in most of the SoCs. However the Exynos4210 flavor actually differs by number of interrupts.
Add new compatibles, maintaining backward compatibility with Exynos4210, and constraints for number of interrupts. This allows to exactly match the Exynos MCT hardware.
