Input: i8042 - add Sony Vaio VGN-FZ240E to the nomux list
On this model, when KBD is in active multiplexing mode, acknowledgements to reset and get ID commands issued on KBD port sometimes are delivered to AUX3 port (touchpad) which messes up device detection. Legacy KBC mode works fine and since there are no external PS/2 ports on this laptop and no support for docking station we can safely disable active MUX mode.
