This adds the basic SoC .dtsi devicetree stub for the Allwinner T113s SoC. This shares a die with the Allwinner D1 SoC (with RISC-V cores), but uses two Cortex-A7 cores instead of the T-HEAD C906 RISC-V core.
Include the existing D1 devicetree stub, but add the ARM specific nodes, like for the CPU, the arch timer and the GIC.
