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.
