drivers/rtc/rtc-twl.c: return correct RTC event from ISR
Following changes are made as part of this change: 1. As TWL RTC supports periodic interrupt, the correct event should be RTC_PF instead of RTC_UF. 2. No need to initialize variable "events" to 0 & then OR it with the event values. Hence fixing it.
