drivers/rtc/rtc-twl.c: fix missing device_init_wakeup() when booted with device tree
When booted in legacy mode device_init_wakeup() gets called by drivers/mfd/twl-core.c when the children are initialized. However, when booted using device tree, the children are created with of_platform_populate() instead add_children(). This means that the RTC driver will not have device_init_wakeup() set, and we need to call it from the driver probe like RTC drivers typically do. Without this we cannot test PM wake-up events on omaps for cases where there may not be any physical wake-up event.
