mwifiex: report wakeup for wowlan 



Register the WLAN device as a wakeup source since it can
wake the system via wake-on-wireless-lan. In an actual wowlan
event, notify the PM core that we are the current wakeup source.
This allows the PM core to update the wakeup attributes in /sys.

This was causing wakeup issues on chromeos as the system was
apparently confused about the wakeup source.
