mb/lenovo/x200: Correct device tree override logic
If a device node should be enabled on some variants, but disabled on
others, it had better be declared as disabled (rather than absent) in
base device tree (rather than override tree for the variant disabling
it), and enabled in override tree for the variant needing it, so that
it does not need to be declared once more when adding another variant
with such node disabled.
