Subject: [PATCH 5/6] clocksource/drivers/bcm_kona: Add the COMPILE_TEST option

Change the Kconfig option logic to fullfil with the current approach.

A new Kconfig option is added, CONFIG_BCM_KONA_TIMER and is selected by the
platform. Then the clocksource's Kconfig is changed to make this option
selectable by the user if the COMPILE_TEST option is set. Otherwise, it is
up to the platform's Kconfig to select the timer.

The timer uses <asm/mach/time.h>, which is now only for ARM, so this
driver will depend on ARM.
