clocksource/drivers/exynosy: Depend on sub-architecture for Exynos MCT and Samsung PWM
The Exynos MCT and Samsung PWM Timer clocksource drivers are not usable on anything else than Samsung Exynos, S3C or S5P SoC platforms. These are integral parts of a SoC. Even though the drivers are not user selectable, still document the hardware architecture explicitly with depends on ARCH_EXYNOS and others. This also serves a purpose of documenting use-case, if someone ever wonders whether to select the driver for his platform. No functional change, because drivers are already selected by the platform described in depends. We follow similar approach also for other SoC-specific drivers.
