    8042 keyboard: power button processing
    
    power button is usually dropped because it's not
    in the keyboard matrix range.  Adding in condition
    to forward it like other keys.
    
    BUG=chrome-os-partner:61275
    BRANCH=None
    TEST=reboot and make sure power button selection
         in detachable menus is processed on reef.
