> SPL also has an option to remove some DT properties which are useless for
> SPL to make DT even smaller.
> Default DT properties are pinctrl-0 pinctrl-names interrupt-parent
> interrupts which are already removed.
> The patch extends this list with iommus to get rid of above warnings.
> Also power-domains unused properties can be removed.
