Input: twl4030-pwrbutton - ensure a wakeup event is recorded.

commit c42bfd7f6cd26e8f712fc184460e32845d928d17 upstream.

This button is treated as a wakeup source, so we need to initialise it
correctly.

Without the device_init_wakeup() call, dev->power.wakeup will
be NULL, and pm_wakeup_event() will do nothing.
