RINGACC module on K3 SoCs have CFG register region which is usually configured by a Device Management firmware. But certain entities such as bootloader (like U-Boot) may have to access them directly. Describe this region in the binding documentation for completeness of module description. Keep the binding compatible with existing DTS files by requiring first four regions to be present at least.
