Add support for fan button on Ideapad Z580
The patch adds support for fan control button on Ideapad Z580. This is the same button as on Z570, but it raises different bit in VPCCMD_R_SPECIAL_BUTTONS. Also add message to dmesg when unknown button press detected, it will help adding support for new special buttons.
