time: Define dummy functions for the generic sched clock
When we try to compile a clocksource driver with the COMPILE_TEST option, we can't select the GENERIC_SCHED_CLOCK because the sched_clock() symbol will be duplicated with the one defined for the x86. In order to fix that, we don't select the GENERIC_SCHED_CLOCK in the driver Kconfig's file but we define some empty functions for the different symbols in order to prevent the unresolved ones. This patch fixes the COMPILE_TEST option for the compile test coverage for the clocksource drivers. Without this patch, we can't add the COMPILE_TEST option for the clocksource drivers using the GENERIC_SCHED_CLOCK. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
