commit a60e6c3918d20848906ffcdfcf72ca6a8cfbcf2e upstream.
When closing the laptop lid with an external screen connected, the mouse pointer has a constant movement to the lower right corner. Opening the lid again stops this movement, but after that the touchpad does no longer register clicks.
The touchpad is connected both via i2c-hid and PS/2, the predecessor of this device (NS70MU) has the same layout in this regard and also strange behaviour caused by the psmouse and the i2c-hid driver fighting over touchpad control. This fix is reusing the same workaround by just disabling the PS/2 aux port, that is only used by the touchpad, to give the i2c-hid driver the lone control over the touchpad.
v2: Rebased on current master
