ROG means ASUS "Republic of Gamers" laptops. The input device info
also represents itself as "ASASTeK COMPUTER INC. ROG MacroKey". It
uses special HID_USAGE code for function keys. This commit remap the
special code to standard keycode for function keys handling. It's
verified on GL553VD/VE, GL753VD/VE.
