[PATCH] clockevents/drivers/timer-stm32: Fix build error spotted by kbuild test robot

[Maxime Coquelin <mcoquelin.stm32@gmail.com>]

This patch fixes below error spotted by kbuild test robot when building
with ARCH=ia64:

All error/warnings (new ones prefixed by >>):

        drivers/clocksource/timer-stm32.c:38:28: error: field 'evtdev' has incomplete type

     struct clock_event_device evtdev;
                               ^

        drivers/clocksource/timer-stm32.c:44:19: warning: 'enum clock_event_mode' declared inside parameter list

               struct clock_event_device *evtdev)

The fix consists in making the STM32 timer depend on GENERIC_CLOCKEVENTS.
