drivers/rtc/rtc-omap.c: add rtc wakeup support to alarm events
On some platforms (like AM33xx), a special register (RTC_IRQWAKEEN) is
available to enable Alarm Wakeup feature. This register needs to be
properly handled for the rtcwake to work properly.
Platforms using such IP should set "ti,am3352-rtc" in rtc device dt
compatibility node.
