On STM32F0, a single IRQ is used for all RTC events, including RTC_ALARM and RTC_WAKEUP, and this IRQ is named RTC_WAKEUP. We use RTC_WAKEUP IRQ in our code while we actually meant to capture RTC alarm event. On STM32F3, RTC_WAKEUP and RTC_ALARM are separate IRQs and thus we're having problem. Let's make it explicit which RTC IRQ we want to use and fix our code to use RTC_ALARM. BRANCH=None BUG=chrome-os-partner:33219 TEST=Run 'rtc_alarm' on Ryu and verify the EC gets interrupted after a second.
