Tony Lindgren - May 21, 2013, 9:40 p.m.
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.

This fix is for the -rc cycle please.
