The Allwinner T113-s SoC is apparently using the same (or at least a very
similar) die as the D1/D1s, but replaces the single RISC-V core with
two Arm Cortex-A7 cores.
Since the D1 core .dtsi already describes all common peripherals, we
just need a DT describing the ARM specific peripherals: the CPU cores,
the Generic Timer, the GIC and the PMU.
We include the core .dtsi directly from the riscv DT directory.
