clockevents/drivers/timer-stm32: Fix build warning spotted by kbuild test robot
This patch fixes below warning spotted by kbuild test robot when building with ARCH=powerpc: drivers/clocksource/timer-stm32.c: In function 'stm32_clockevent_init': >> drivers/clocksource/timer-stm32.c:140:9: warning: large integer implicitly truncated to unsigned type [-Woverflow] writel_relaxed(~0UL, data->base + TIM_ARR); The fix consists in using 0U instead of 0UL.
