Replace DTS file

Modify the target/linux/mediatek/image/mt7988.mk

define Device/santi-dsa-10g-spim-nand
  DEVICE_VENDOR := santi

Put the DTS into build_dir

cp dts_files/*.dts* openwrt/build_dir/target-aarch64_cortex-a53_musl/linux-mediatek_mt7988/linux-5.4.260/scripts/dtc/include-prefixes/arm64/mediatek/

Coding Style

Use clang-format to fix the coding style

cd santi_uio
clang-format -i src/*.c
