dt-bindings: treewide: add access-controllers description
access-controllers is an optional property that allows a peripheral to refer to one or more domain access controller(s). Description of this property is added to all peripheral binding files of the peripheral under the STM32 firewall controller. It allows an accurate representation of the hardware, where various peripherals are connected to a firewall bus. The firewall can then check the peripheral accesses before allowing its device to probe.
