Some IPQ4019 boards like Google WiFI have it enabled as well. Luckily, SDI can be disabled via an SCM call. So, lets use the boolean DT property to identify boards that have SDI enabled by default and use the SCM call to disable SDI during SCM probe. It is important to disable it as soon as possible as we might have a WDT assertion at any time which would then leave the board in debug mode, thus disabling it during SCM removal is not enough.
