T440P: Add FN Lock inversion

The current f1 to f12 as primary just enables FN Lock and causes a light to enable on the keyboard of the T440P.
Newer machine firmware has the option to invert FN Lock so that the unlocked state has the light on and locked has
it off. This way you have no light and can use the F keys instead of hotkeys unless you hold FN or enable FN lock.

Obviously now we don't want FN lock on by default. This was tested on both the T440P and X250 so should be present in
all thinkpads with a FN light that had the option in the bios.
