Add a defconfig for the Allwinner Nezha, a raspberrypi-style board built around the RISC-V 64bit D1 SoC. There is currently no upstream support, so use the git repos from Samuel Holland as explained on the linux-sunxi wiki: https://linux-sunxi.org/Allwinner_Nezha The U-Boot DTB is also used by opensbi, but the two branches are unfortunately not in sync at the moment, so add a patch to fix the compatible for the PLIC so opensbi makes it available to S-Mode (Linux). The use of the sun20i-d1-spl SPL bootloader / TOC1 file format also makes it a bit more complicated to build the boot image. As this is expected to only be a temporary issue, add a U-Boot patch to build the TOC1 image as part of the build rather than adding explicit support in our U-Boot package to do it.
