CLKSRC_EXYNOS_MCT option is not visible unless COMPILE_TEST is enabled. Select CLKSRC_EXYNOS_MCT option for ARM64 ARCH_EXYNOS like it's done in arch/arm/mach-exynos/Kconfig, to enable MCT timer support for ARM64 Exynos SoCs. Even though ARM architected timer is available on all ARM64 SoCs, and used for managing timer hardware and clock source events, MCT timer still can be used as a wakeup source, as stated in commitae460fd9164b ("clocksource/drivers/exynos_mct: Prioritise Arm arch timer on arm64"). It's also nice to be able to test available MCT IP-core.
