Adopt the kernel device tree directly from dts/upstream/src/riscv/spacemit/k1-bananapi-f3.dts instead of carrying a forked copy under arch/riscv/dts/.
The U-Boot-only overlay k1-bananapi-f3-u-boot.dtsi carries the binman description and a memory@0 node, since the upstream kernel DT has no memory node (RAM is filled in by the bootloader).
