mb/lenovo/x201: Support undock button on X200 ultrabase
Only the ACPI code needs to be extended, as smihandler.c already
supported it. The _Q50 Method is just _Q18 with changed name.
On Linux, pressing the undock button does nothing, so the only safe
way to undock is to press Fn+F9. With this patch, when the undock
button is pressed, the green LED lights up, and undocking is safe.
