rtc: da9063: add as wakeup source

    rtc: da9063: add as wakeup source

    As da9063 RTC is not a real I2C client, but relies on da9063 MFD
    driver, we need to explicitly mark da9063 RTC as a wakeup source
    to be able to access class/rtc/rtcN/wakealarm sysfs entry
    to set alarms, so we can wakeup from SHUTDOWN/RTC/DELIVERY mode.

    As da9063 driver refuses to load without irq, we simply add it
    as a wakeup source before registering rtc device.
