clocksource/drivers/clps_711x: Add the COMPILE_TEST option

dlezcano · dlezcano · commit 250e46aa3bb3 · 2016-06-20T23:22:20.000+02:00
Change the Kconfig option logic to fullfil with the current approach.

A new Kconfig option is added, CONFIG_CLPS711X_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.
