The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of RTC alarms 0 and 1 were inversed between these two devices. So when rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to S2MPS11_IRQ_RTCA1, not RTCA0.
Fix this by using consistent RTC alarm interrupt numbers and adding a BUILD_BUG_ON for future generations.
