The so called "system controller" in Allwinner A20 and A31 SoCs is multi-purpose controller that tries to add misc functionality to one memory region. In these SoCs it controls the internal SRAM partitioning but it also includes registers for chip versioning and NMI control. This patch adds the proper nodes in the DTS files and enable the syscon in the defconfig files.
Even though the system controller includes also register for managing the NMI controller, these register are not mapped in the syscon since they are directly used and mapped by the NMI controller itself.
