nezha_defconfig: bump u-boot to current top of d1-wip

This is now based on U-Boot 2022.10 and has gained SPL support, so use that
instead of sun20-d1-spl.  With this we can also drop the u-boot patch and
patch directory.

-Subject: [PATCH] Makefile: HACK: Support building u-boot.toc1 for nezda board
-
-For easier integration into Buildroot.  The boot0 / toc1 logic is WIP until
-U-Boot gains SPL support for the D1, so add a hack to make it easier to
-integrate in Buildroot as-is.
