configs: add rk3308-aarch32_defconfig

What's different with evb-aarch32-rk3308_defconfig?

- it enables CONFIG_USING_KERNEL_DTB to use kernel dtb;
- it doesn't care much about boot time and image size;
- it can be used for most rk3308 aarch32 board that doesn't have
  very critial quirements on boot time and image size.
