wilc1000: add new WID to pass wake_enable information to firmware

Add new WID(WID_WOWLAN_TRIGGER) to send wake_enable information to firmware.
In 'set_wakeup' cfg80211_ops callback, the enable information was not
passed to firmware which is required to handle WOWLan trigger notification
from firmware.
