Subject: [PATCH 1/5] LoongArch: Clean up loongson3_defconfig

There are many unnecessary configs in loongson3_defconfig, clean up it
with the following steps:

  make defconfig
  make savedefconfig
  cp defconfig arch/loongarch/configs/loongson3_defconfig

Then we can get a clear diff if the defconfig is changed.
