Ok, in this case I suggest adding a new property so that the switches
can be turned off only when the new property is present.

When this new property is absent, then we keep the current behavior
and avoid dtb breakage.

Since MX8M support is not in place yet, this is not urgent, so I will
send a revert and then you can re-work the patch so that it does not
affect the old dtbs.

Do you agree with such approach?
