Subject: [PATCH 32/69] clocksource/drivers/exynos_mct: Fix Kconfig and add COMPILE_TEST option

Let the platform's Kconfig to select the clock instead of having a reverse
dependency from the driver to the platform options.

Add the COMPILE_TEST option for the compilation test coverage. Due to the
non portable 'delay' code, this driver is only compilable on ARM.
