This copies in some devicetree files from the official Linux kernel tree, v6.6-rc6. It covers a board with the Allwinner T113s SoC, which shares many devices with its RISC-V sibling, the Allwinner D1(s). This is the reason for the core .dtsi files landing in the arch/riscv directory. We are only adjusting the include path to accommodate for the differences in the U-Boot build system.
