davinci: da8xx/omap-l1: mark RTC as a wakeup source
On da850, RTC alarm is a wakeup source from deep sleep. Mark it as a wakeup source after the rtc platform device is registered. Without this patch, the rtc-omap driver suspends the RTC during the suspend sequence and hence it cannot wakeup the SoC.
