Subject: [PATCH v2] rtc: da9063: add as wakeup source

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

v1->v2:
Alexandre Belloni:

Dropped everything except device_init_wakeup, as driver refuses to load
without irq specified, we can always set it as a wakeup source, before
calling devm_rtc_register_device.
